Manufacturer: WATERMAN (USA)
Model: AN UPM-45, S#???
Vintage: 1950
Purpose: General Purpose, Dual CRT, Military
Condition: Original, Working
Comments:
This is a military scope, with 2x 3SP1 CRTs to allow viewing two signals at the same time. At first sight, this looks very similar to the S-15-A by Waterman and I am sure there are a lot of similarities. But obvious are the differences in operation elements and tube lineup. It would be interesting to know who was first, this one or the S-15-A. I doubt there were many made or used of this scope because I can not find any information about this scope online. If you have any information, please contact me.
