Love this blaster! Congrats on the RO72.

To my knowledge there are only a couple original parts that have been found. The rear end of the scope is an Emerson or Fada knob from an old radio. Search "bakelite knob" etc on eBay, they're not too hard to find (and in various colors!). I think the scope is based on some kind of electronics probe, but it hasn't been identified (and I've SEARCHED). The plates on the sides have a half of a bomb from a Revell 1/32 F4 Phantom, and the classic "motor coil" greeblie from the Revell Visible V-8 that's all over a bunch of blasters. That's all I've got, but I can add that the rear site on the RO72 is on the ROTJ E-11s.

The thingie on the flipped front scope at the end of the barrel, I think it's a marker cap, or maybe a wire nut. Haven't found a match.
Correllian Exports did a run of side plates and scopes, I think Vince still has some. I'm currently working on one of these and have modeled all of the greeblies and scope for resin printing. I can help with parts if you like, just PM me. Here's mine with 3d printed greeblies and scope. Everything's just laying on there so not quite in the right spot. It's a real radio knob, and the plates are CE, I filed the shapes a bit to be more accurate).
