This is only first reason of rarity of this scope. But there is a second. There are NO afterwar repair marks on this scope. Repair marks on scope means that it was tested and maintained at plant after war (in 1960 years). There are additional characters, signs and dates applied at scope tube.
Means mechanics maintenance, triangle with a number inside 25 - repair at 25 arsenal, - lens repair, - replacement of mechanics, square crossed out inside - complete disassembly of the case and repair, an additional digital designation of the year (after wartime - for example, "1968") next to the year of manufacture or with the main hallmark of the plant - means the year of the last repair. There are no any repair mark on this scope, so, it means that this is original early PU scope without any touching since production! There is an original native 1940 tube, original non-illuminated 1940 lenses! And scope is fully operational! First ever made PU scope, in 1940.Made in Kharkov plant (where PU scopes was originally designed). Kharkov scopes are rarest because plant was evacuated after beginning of war. Only 1% of PU scopes was made in Kharkov plant. No afterwar repair marks - means that scope is in native 1940 condition. We never see such scope and there is only one such scope in stock.
Maybe only one on world market. So, take your chance to take it. Original base with pins and screws.
