Photograph number 55 on this page is new to me.

Was Russian use previously known?

Neil,

No, Russian use was known. They received three of the 415 example built. One of them still survives at the museum at the Museum of Armoured Forces, Kubinka, Russia.

That period picture was new to me as well, though! Thanks for posting it here.
