Solar CB-1-60 Capacitor Analyzer Questions

[powerking]

Howdy all,

I just joined Videokarma and was looking for some info on this analyzer. I'm mid-stream in rebuilding/restoring it and was wondering if there is any way to date this (approximately)? It is SN=8351. I've read on the net that this model was produced ~~ 1936 through 1945?? This one has the smaller 2mm pin type test jacks and from other pictures, I've seen it looks like later models used the more standard 4mm bananna type?? Also, the tube sockets use nuts & screws where (I guess) later versions were riveted in? I think Bob Andersen's unit had this type as well as a factory 6X5 type rectifier? Mine is the 4 pin type-IV tube. Waiting for some 1% film caps from Mouser (back-ordered till the end of this month .

Any help appreciated.
