Russian 635P?

A few years ago when I was hunting around for 6C45P tubes, the (Russian) dealer I was purchasing from told me I should also try the 635P, some of which I bought. Does anyone know anything about this tube? Can anyone point me to a data sheet? It's a tall, v. rugged 9-pin single triode. Looks like 7W or so dissipation.
 
Oops, I didn't look carefully enough at that data sheet. It's not the data sheet for my tube, which has 635P written on it.

It is this tube: 6Э5П, RF tetrode:

Data is in Russian, however it should be easy to translate. Apparently it is an equivalent of EL183.

P.S. - found a datasheet as a picture:
