I just went though Jedi last night looking for the MOM control box and other greeblies
There are 2 MGC DL44s on set in endor, plus the stembridge. When the rebels free themselves and start the battle, Han swoops down to 2 of his blasters on the ground and picks one. I dont remember though... the color of the grips
The scopes are weird, i think the gun with the missing front half is a real scope bell. Still unidentified
also the auction blaster has a very detailed back half and I cant tell... but it feels like a real one.
confirmed from the guy who bought leftover resin bits from filming via an auction, the scopes with no lens retainer line around the rim and a thin/non beveled rim and a flat internal lens are solid lathes derlin. Neither the auction DL44 or the "missing scope" one have dark flat lenses... if this makes sense
