This action was developed on the request of the Germans during occupation in 1943. A very few were built as full stock 98k type trainers. None are known to have left the country in that configuration and possibly only a handful of examples may exist in the Czech Republic. The recievers of these were marked "tgf" a code assigned by the Heereswaffenamt.
Production was halted and capability dedicated to combat weapons due to the winds of war. A large stockpile of parts and receivers were left over. Sometime after the war (appears mainly 1949 and 1950)
These parts were used along with new barrels and stocks to make the Model 1. Some of these still have the German code "tgf". (I have one in un-issued condition). Most went to Czechoslovakia and other eastern block countries as military training rifles. Deluxe sporters were made in same configuration with a different front sights, deluxe wood and and checkered grips. (I have one that came out Sweden). Few of the commercially marketed guns came to the US as import tarrifs on Communists goods rendered them non-competive price wise. Total production may have been as few as 65K or less. Other models were made. The action was slightly modified and numerous versions made up through the sixties and seventies. The basic design is the basis of the CZ452 series currently produced. These are not actually BRNO as this company no longer exists. License for the design was sold to CZ.
Many variations of this action were made by BRNO and went largely although not exclusively to Communist satellite countries.
The Model 1's sold by J&G came out of Romania. Only 250 were imported. The Czech Republic will not allow used military guns to be exported.
My deluxe Model 1 cost me just under $600 and with the exception of the front sight and plain wood, the J&G trainers are the same gun and equal in metal machine work and finish.
My "tgf" and 3 other un-issued Model 1's cost me just under $400 each.
These will not be flooding the market like the Romanian 69 and others. In the first place, there were never as many made, and in the second place only a few were available for importation and that source likely has dried-up. I would not rule out a few other BRNO .22 variants showing up, but not these and not as nice.
Congratulations to everyone who got one! I will post more information as I obtain it and correct anything I subsequently find out to have been in error. Much of the history on this period in BRNO's history is still cloaked in secrecy and official records have still not been released.
