Here is an oddball for you.
I guess International Servicemaster (a well-known tube rebrander) really needed 7F7s but had none in stock, so they took a GE 6SL7GT, removed the base, and hardwired it into a 7F7 adapter.
I actually have a few of these.
Did they do this to any other tubes?
Follow Ups:
I have some tubes labeled 12bh7.
They have a wafer at the bottom to "re-pin" it is so it's "clocked" like a 12bh7.
Someone said it might be a 6350. The 6350 data sheet looks a little better than a 12bh7. They look like nice black plate tubes.

I did this work about 7 or 8 years ago. Shaved off the original key, then cut a groove and installed a new key made of G10 rod. Finished the work with a coat of gloss black automotive-grade enamel. I reworked 22 of these fine NOS tubes, and have since purchased a few more that will eventually get the same treatment. Looking forward to finally putting them to use in the amps I'm building now.

7 series tubes usually bail out audiophiles replacing 6 series tubes. Best example are Sylvania oval plate 7C5 tubes. They are same plate as a Sylvania 6V6G. $10 for the NOS 7C5, over $60 for the NOS 6V6G if you can find them. The old Sylvania 6V6G are great sounding vs the square edge newer Sylvania 6V6GT. Some 7C5s has the newer plates.
