I can't identify type of tube this is, I've checked numbering systems and it isn't there hoping someone with expertise can help. The tube is an RCA 8CS7, on the box lid it says, 32R5-R, Then below that it says, (9-60)
OP Here, to clarify I wish to know what it use is.
it's for tubing vacuums
it's for an old television.

Confirmed. It's for TVs.
Or you can do what I did and use a foil wrap to make it fit in our torque tube machine from 1956

(OP) Ok, thanks I was thinking it was for something of that source.
