Question about 15GP22 production

[miniman82]

Answer: both, not that it matters.

Even a ‘machine’ weld in those days was still a manually controlled TIG weld, and any holes found by the leak detector would have to be fixed by hand.

Thanks Nick. Bob mentioned to me that the later 15Gs seem to have a lower leak rate in his opinion.

Does anyone know when production started and stopped? I'm more interested in knowing how long the tube was actually built.

My 1964 Allied still listed a 15GP22 for $222.00. IDK, if it was NOS or recently manufactured.
The newest type listed was a 21FBP22.

Ben, the oldest 15GP22 I know of has a date code for the fourth week of 1954.

That's a bit younger than I was expecting. Thanks Pete.

It kind of pokes a hole in the hypothesis that the Admiral set was the first commercially available color set: Admiral would not have been selling sets with prototype jugs to the public, and if the oldest known production 15GP22 is from the fourth week of 1954, then nobody could have commercially released a set before then. You've gotta have CRTs to put in 'em...

I have a 1965 Allied catalog that does NOT list a 15GP22 in its CRT pages. That might be one indication of when new or rebuilt 15G's stopped becoming available.
