Thanks, Michael.

"When you look at tubes to get an idea who made them,there is many times a three digit number prefix on the tube somewhere or 4 digit.
For instance if its 188-5 the tube is a GE
If its 274 its RCA
If its 312 its a sylvania
If its 322 its a Tung sol"

Interesting. Unfortunately on these Stromberg-Carlson ones, almost everything has been smeared off into illegibility. I can, however barely make out the "Stromberg Carlson" on one of them. The "5963" and the "Made in USA" seem to be stenciled on.

Are those numbers valid for all types of tubes or are those only for 12AU7/5814/6189 & 5963 types?

Is there a webpage or url which has the table of those manufacturer's IDs?

Thanks again.

Jeff
