Okay , So here is what I have left now.
I have a mismatched set of Phillips and Tungsol. The structure is very similar and the both use horizontal getters. They have the same style of flashing. There is a difference in the angle of the getter support. My guess is same factory, different date. Test 82-120 Phillips and 109-120 Tungsol.
I have a pair of RCAs that test 75-108 and 98-117.
I have a single RCA Victor that tests 115-82
My take is that since the sections are used in parallel, matching is not that important. You be the judge.
