[R-390] USM 25 // Question

[shadow]

Hello from Silicon Valley..

I was rooming around the flea market friday morning hunting for Audio
and RF Gear. I found a USM 25F  / SG 103 generator with the cover.
Not matching numbers, but I'm no collector.
The cover did not have any accessories at all. ZERO.

When I arrived back at the Lab. I just had to look inside. Just
beautiful inside. If it has been serviced and I'm sure it has been many
times for its age. It just perfect inside. There is not even a scuff on
any of the screws. Someone knew what they were doing.
Defiantly more beautiful on the inside then outside.

So....  I powered it up with a varaic and it looks to be working unit,
very correctly. Hard to believe something that old can work so well, but
that why the are called precision test equipment.

I need to know if any of the accessories even necessary for general use?

If so...  Then I will look at more flea markets or build them.
I just need to know what they are.

I know the USM 25's  are popular with the group. Seems like a good place
to as a question.

I have had lots of military stuff in my life, just not may signal
generators.

The best part is the it came from a seller I knew. I always said hello
and looked at his booth, even when I knew there was nothing I wanted.
He chased me down as I walked by, pulled me to has booth.
Just pointed and said...  "This is yours, take it with you and make sure
you do"

Sometime.... Just being nice to people has it rewards..

Thanks Guys..  For any information you can supply... Will be helpful.
