[Milsurplus] Re: URM-32

Hi

Well mine has the ever valuable CBS Hytron tube puller so I guess I'm 
one up on you in the *rare* race.

As far as I can tell the 102x models were commercial gear. I can't say 
I ever remember a Divco anything except a milk truck so they must not 
have been all that successful.

The power supply is an interesting twist. I don't know how many of the 
military units went out of Divco with batteries and how many with power 
supplies.

You mentioned the spare tubes in the back of the case. I took a look at 
mine and they all had date codes from the year 1959. Either somebody 
went to the trouble of re-stocking the spare tubes or the unit shipped 
about three years late on a 1956 contract. I think I would bet on the 
three years late theory.

	Take Care!
