Zima spring pistol

Zima spring pistol 

With thanks to John G.

He says:

Two examples of the following pistol are known to date. One cropped up on a Swedish airgun website and another was purchased in Spain. They are clearly labelled “ZIMA”, but there are no other markings on the pistol, other than what is presumably a serial number stamped on the foot of the grip, so its country of origin and manufacturer remain a mystery. The two known serial numbers are 55 and 79, so it is reasonable to assume that only a small number were made, hence there rarity...

The Czech suggestion prompted me to use Google Translate to find out if any other languages use this word, and I was surprised that almost all of the Eastern European countries use the word Zima, and also Sweden. Although there is no Z in Russian and Hungarian, the same word is also there, and if Romanised would also have been written as Zima. In all these languages it has the same meaning "Winter" or Wintertime". I suppose it is a reasonable name for an air pistol, just a bit less aggressive than our Tempests, Tornados, Thunderbolts etc.

The pistol seems to be relatively crudely made. Both examples have the cylinder end cap unnecessarily exposing a lot of excess thread. The grip stippling on the one is distinctly amateur, and while the other pistol has a checkered grip, it is a simple heavy machine cut pattern. The crude construction, IMO, seems to exclude Sweden, Czech Republic , Poland or Hungary as likely contenders. The pistol could more likely be Russian or from one of the smaller Eastern European countries, and was probably made in the austerity Cold War period.
