Ok, thanks. I thought maybe I wasn't paying attention and missed a bunch of info. Is that pulley the same one from the record player they used?
20 years ago my dad had a real functional Mauser and was selling it to focus mostly on U.S. Civil War weapons and he asked me if I wanted it. I couldn't see using it and potentially messing it up! There's probably a lot of them, but still.
The prop dept. didn´t cannibalize any record players, but simply purchased a sh*tload of parts from Transcriptor back the days. So they had pulley discs, knobs, sweeparm parts én masse
The pulley disc on the MS blaster is nearly identical to the ones found on imperial hats , belts, ANH DH17 etc., but has a smaller O.D. IIRC
