Pommel cubes were flipped, And possibly missing the cap, I don’t know about the grenade... it does look awfully different to what reference we have.Is it true that the Tunisia prop had the male balance pipe and the grenade flipped? the photos I've seen sure seem to point in that direction.
Throw up a pic and flesh out your hypothesis. The grenade looked flipped to me in the cantina scene at one time so I’m favorable to the two heros idea to a point.
