They were on ebay! Complete NOS vacuum packed with serial numbered datasheet/manual! I think I bought the last 2. If they work it's very nice but who knows after 35 years storage

They are in production by Baspik in Vladykalkaz:

The company has a whole range of detectors, image intensifiers and phosphor screens at good prices (I'm not related to the company - I just made some sensor quotations from them at work).

Unfortunately I don't know the material and it is nit stated in the data sheet.
