Help me indentify a tube please

[foo_3001]

I was digging through my "NOS-box" where I´ve stashed the NOS tubes I´ve bought through the years. As there´s only pre tubes they last very long so I tend to forget what´s in there..

Found this one, a tube with no stamp, really long plate etc, no idea what tube this might be.. No idea what type even. I bought a few Telefunken ECC83s a few years back, not sure if this could be one of them..

Any help would be greatly appreciated!

Here´s a few pics, hope they help some.

At first glance I was thinking that looks to be a 5965/12av7 from the plate structure, but given the mica and internals, it is possible that it is a JJ/tesla 803s type as well

I believe Telefunken tubes had a diamond in the glass in the middle of the pins on the bottom. Your last pic is so bad I can't see anything.
