Gruen Master

I think the Quadrons 117-123 were also truly in-house, because of the way the serial numbers mesh with the pocket watches.

I am certain that the V4-7 and UV/UV390 were in-house; not actually sure about the earlier versions (V1-3). Regardless, the design is Gruen's.

This has been a great thread to read.
