This is a Motorola S1339A RF Millivolt Meter I got from a friend. It was a piece of gear that his late dad had, and was packed away in a barn. It's actually a Boonton 92E that they rebadged for Motorola. This is an excellent RF millivolt meter. It had years of dust/dirt from the barn, and even had a large mud dobber nest inside. I cleaned it up and found it was partially disassembled, perhaps being repaired when it was parked. I repaired an issue with a socket for an op-amp chip, found fasteners to reassemble it, and calibrated it. The cases got a shot of paint, and it works like new. It's a great piece of test gear!
