Just to clarify I would never use Comic Sans so it probably wasn't me :lol
BUT these are pics of the eight you will hear talked about (in no order):
Bill George Y-wing. Made by Bill when he was a young fan, not yet hired by ILM, then "drafted into service" during ROTJ when they needed more Ys. Now living at the Archives and technically Canon. Proportions are unique, and the R5 is the biggest landmark:
"TIE Killer" or Gold Leader. This is a Hero ANH Y, in private hands now, and I suspect it has been painted "post filming" in a few areas. I may be in the minority on that one, but I don't think the green is screen-seen (and it's sloppy as heck). Every one is real skittish about this one, which leads me to believe the owner is paranoid about the provenance of how or why it is in private hands now.
The Alan Ladd Jr Y, hero ANH, given to Laddy after the film wrapped and later sold to the owner of Prop Store, who I assume will be buried with it. I know I would! A GORGEOUS example of the original wave of Y-Wings, and it has a pilot!
Colin Cantwell's Y-Wing Prototype. This pic has guns and a canopy that seem to be a design that was laster changed, as it does not look like this now. Also still in the LFL Archives.
Ugly terrible crappy "pyros" or deep background Ys. They are on "sticks" permanently, they are painted crudely, they are beat to hell, and they live at the Archives as well.
Red Leader, or "Red Jammer". This is the first Y-Wing built incompletely and shipped to Elstree with the Blue 1 X-Wing for use by the set designers to make the 1:1 set pieces. It was returned to ILM and finished (uniquely) at some point, but did NOT see screen time (unlike it's companion which became Red 2 and was filmed), It lives at the Archives and I think is the only Y with styrene engines.
"Blue R2 with Red Stripe" Y-Wing. The only Hero screen used ANH era Y that is still in the Archives. This one toured and was the first one I saw at the Smithsonian in the 1990s. It was also on tour when I was doing the reference at the Archives for MR, so this one is a show pony!
Triangles. My white whale. I recently scored high res four-ways of this one, and I have a back shot too, so I can now say we have nailed the paint work on this puppy, and all the decals on the underside. She was a pyro, she was wonky and her neck drooped, and she blew up. Shuffled off this mortal coil. An ex-parrot.
