I've had three of these telegraphs during my time, and hung on to two of them.
Lucky.

I had all of the parts -- even an acceptable airsoft Uzi I could use as a base if I got everything else while hanging on for a Marushin -- except that one. I was hunting for literally almost twenty years for one. I'm willing to bet one of y'all always managed to scoop me on it. I've had several occasions where I found one not too long after it sold.
For my next trick, I need to replicate the "telegraph key", but come up with some "swarzy" reason for it to be there. This is the top of the blaster barrel shroud. What function does it serve besides potentially getting in the way of the sights? And, speaking of, I'm still torn between bending the rabbit ears together versus leaving them and putting a sight blade between them.
This is my whole "more accurate than the movie version" at play. I also converted all the black markings on the aluminum plate into slots. The knob turns that red mark in the arc, and I want to engrave tiny marks along that arc. Safe, single fire, burst, auto? Akin to the Mauser M712 or Sterling L2A3? Stun setting? Or should that be one of the other "controls'" features? Tempted to run a coiled wire from the Paterson handle to the grip assembly, in the manner of the Merr-Sonn pistols and several of the E-11s' "power cylinders" (which I feel are more likely part of the aim-assist apparatus). This became one of my favorite blasters the very first time I saw it.
