Well I return to this thread today since lock down has most of us locked in an pretty bored
Im going to try and put out a Time line of basically the Vader helmet story from research I made
would love to hear input from other Vader collectors but this is how I believe it all went down
The path of Vader's helmet as I have it to my knowledge as follows
Production for ANH starts Mr Muir using a cast of David Prowse Shoulders and head
sculpts a face mask in clay over David Prowse plaster cast using a small side sketch of Vader's helmet
provide by John Mollo
The Mask is sculpted Asymmetrically giving Vader that perfect organic real look
not that weird look of the Rots
The tusks on the side of the mask was sculpted after the Mask and then added onto the mask
by Mr Muir as well as two tear ducts beneath each eye in the shape of a half moon
then he sculpt's in clay the dome on top of the face mask
after this the helmet(mask and dome) is casted in plaster
and is further Refined and sharpened by Mr Muir
from there it is taken by other members part of the ANH production
and then further refined by them
Dome and Mask is then molded and casted in fiberglass ( 3 helmets are made for ANH Only one is used onscreen in the movie)
The mask is smooth on top of the crown and receives three 3M Apple connector tabs on top of the crown
that connects to three 3M tabs on the inside of the dome that is mounted on a spacer inside the dome
The mask has foam padding on the inside and 3 elastic bands used to hold the mask to Prows face
the eye lenses is a clear color ( not red)
and the bottom chin triangle is small
The Dome Has a sharp widows peak area
with a indentation and the dome flange area or skirt is thick
The dome sits very low on the ANH mask giving it a nice angry look
the dome center stripe is sharp and quite thin
Both mask and dome is painted gloss black with an automotive gloss black
the mask doesn't pick well up on camera and the mask is painted quickly
with an metallic grey in an alternating pattern by hand with a paint brush
The black cheek has an indentation in the shape of a C called a Cscar

After ANH production The Helmet is molded in two different molds a
US mold (known as the Rick Baker Mold)this mold spawns
helmet's used only for promotion and touring purposes of Darth Vader in the US to promote the release of the movie
Helmet's coming from the US baker mold in fandom is
SL
DJ
EFX
The other mold is known as the UK Mold this mold spawns casts used to make the ESB screen helmet and Rotj screen helmet
Here is where most authentic cast helmets originate from as well from cast's of the UK cast etc
The Casts all start out as perfect copies of the Original screen used ANH Dome and Mask
the mask retains the 3M tab in the new cast's and surface details from the original ANH mask
Uk casts in fandom are
TM
GS/CFO
TD
How the UK cast made ESB and ROTJ helmets to follow
Alright y to continue with the time line
so Star Wars was a huge success and Darth Vader becomes an Icon
the Icon we all know and love
So a mold of the original ANH screen used helmet was molded
The Baker mold in the USA spawns a helmet cast used by Lucas film to promote star wars
Kermit Eller an employee of Don post studios don's the Vader suite wearing helmets from this mold
and the original screen used ANH helmet lands in the hands of a private french collector
Now in 1979 ESB production starts I believe
The Mold called the UK mold is still at the UK production studio Where ILM
makes most of the props for star wars if im correct
This UK mold is a exact copy of the original screen used ANH helmet
it has the three 3m apple tabs still on top of the mask crown
as well as much of the original details found on the Original screen used ANH helmet
small chin vent triangle etc
the Dome is also a copy of the ANH but there might have been
a cast made of the ANH dome modified by the ILM crew
and then Molded as the ESB/ROTJ domes
where this new modified dome was bit shorter in the skirt of the dome
the dome skirt was sanded smaller than the ANH dome skirt
and the center strip was made wider by a small amount than the ANH strip
and the ANH sharp widows peak was cut back/sanded to give it a flat look
and the Y crease of the ANH dome was left in the ESB dome only a little
and the indentation of the center strip as well
The mask came out and ANH mask out of the mold
the ESB crew cut out a wider and bigger chin vent by hand
so Prowse could see better and for air flow
the lenses were changed to a bronzish tinge clear
the mask was cleaned up some what made smoother,sharper etc
Below is an illustration to show what happened to get the new ESB helmet for Vader
Purple line is the widening of the center strip it was made marginal wider and softer
over the ANH strip
Red line was the dome skirt sanding it thinner
I believe the ESB dome was sanded abit shorter in the dome flange from the bottom
but Im in two minds personally that all movie domes were ANH domes with the
changes of the wider dome strip for ESB/ROTJ and the thinner skirt
as well as dome flare correction
Green is the dome flare was brought a bit more inward
it was brought more inwards on Vader's right side our left looking straight on
and then the wider bottom chin vent cut out on the mask
Sharp widows peak sanded/cut back and made flat
Further the ESB crew added a new dome mounting mechanism
on top of the mask crown and inside the dome
this mech was a PVC ring with a smaller diameter ring on top of the mask crown
and a larger diameter ring that fits over the smaller ring inside the dome
the mask also received a piece of Velcro on the forehead
with the connecting piece of Velcro inside the dome for a firmer dome mount
so the dome doesn't fly off like it sometimes did in ANH because of the flimsy 3m tab connection
Because of the new dome mounting mech the ESB dome was also more raised up and sat abit higher
over the nose of vaders mask the dome did not sit so low on vaders nose like in ANH
The tusks sensors on the end of the tusks for the mask remained the same as the ANH mask
only thing is both tusk sensors where silver not like in ANH where the left side one was half blackish
with splotched paint
the mesh inside the mask vent's also changed over ANH in the ESB helmet
and lastly the Mask and Dome was painted smooth with an automotive grade paint
mask was still an alternate color of gloss black and metallic gunmetal grey
only now in ESB it had a sort of polished showroom finish but not perfect finish was still orange peely etc
as well as the dome was painted in a gloss black automotive paint
polished smooth yet not perfect mirror shine smooth
had orange peel and defects in paint job
So the ESB helmet
below is the stunt mask it had a few major differences over the hero ESB mask that I will address
bit latter on
Bit to get the idea of what im taking about one can clearly see the ESB
round PVC dome mount
larger chin vent
etc over the ANH helmet
and new smooth paint job
Next I will post on the ROTJ helmet
But from here it is where things get tricky as I don't want to begin arguments !
So for the production of ESB a few helmets were cast from the UK mold for the production
so they started off ANH and were converted by hand to ESB by the crew as described above
im not sure how many helmets were made I can not say as I have not definitive information on this myself
But off these set amount of helmets made some become Hero helmets worn by Powse as seen in most of ESB
one becomes the blown Luke dark side cave helmet
One became the weird ANH mask / ESB dome helmet seen in the beginning of the movie when vader storms echo base
and one became the stunt helmet used by Bob Anderson for the fight scenes
Now after production they rmade a mold of a ESB helmet and from this they cast
the few ROTJ helmet's used in production for ROTJ
I will go more in details on this next post
But that is the gist of it
as well there were ESB helmets made for touring and promoting purposes but on those I don't know alot of info
perhaps someone can chime in with more details
