Here is my part of this story/prop.
My son Robert E. Coyle did indeed design it. Mainly the main body.
I made the center section. And the big rocker switch was indeed transparent and was rigged to be lighted. Sadly there were only a few in the box of switches at a surplus electronics store here in Phoenix AZ. I never found out the manufacture nor ever found them again.
And yes I used a M16 trispike Flash hider as the mold master and then cast them in fiberglass and sanded them at the angle you see.
I did buy a box of the red bar push buttons we used for the trigger thinking I would do a run of these…what stopped me was not being able to find those rocker switches.
The Bargraph displays really came with the black faces.
I remember both Scott and I working on these.
Scott machined the delrin rods on his Shureline Micro Lathe.
Like the Power Leach/proton Collector I was asked to turn them in unpainted so that the studio paint shop could finish them. They did the painting and added those tricolor strips.
This is one of the very few props I made that I do not own a copy of.
