Thanks John!
That's a nice looking refractor, who is the manufacturer?
That refractor is "ABP-2"
(read AVR), D=200mm, F=3000m. It was bought by observatory in 1960, is used since 1964 for visual observing of lunar occultations, and since 1974 - also for photoelectric observations.
I do know that it is manufactured in USSR, but I don't remember the exact place. Very possible, that it was manufactured at
Kazan Optical and Mechanical Plant (Tatarstan, Russia). At least this fact is true for the same instruments in observatories of Moscow and Rostov-na-Donu (I have just found that info on the web).
