I know this is not a vz.24 as the seller describes it, but which BRNO model is it? The roll stamp on the left sidewall is different than any Model 21/22 I've seen, though the rifle otherwise is similar. Is the 30-06 chambering original? Never seen that either.

BRNO rifle at auction

Don't be confusing Alf with aalf.

Model 22 Sometimes referred to as the 22F or 722 F depending on where the gun was sold.

They come in different formats based on the age, early models had round action rings later models had the typical "Brno" square bridges with dovetail milled into them. A feature kept in the Galas Rifle ( ZG47) and then carried over to the BSA sporting rifle which were manufactured or design influenced when Brno engineers fled to Britain during the war and ended up building the BREN gun.

In the Model 21 / 22 we see variations in small design and milling technique differences on the actions when they are out of the wood.

The action date number suggests 1947 but the barrel stamp 30-06 is not in a stamp used by Brno, its aftermarket so is the rear sight, that too is not Brno. The 21's and 22's were strictly Euro calibers no bigger than 8x60.

The ZG 47 was made in euro calibers but could be special ordered in other calibers. I have a very rare 9.3x64 which was done by Brno with Brno stamps

Some of those small ring Brno 98 like in the link, may not have the typical mauser bolt guide rib, or the corresponding slot in the rear bridge.

Thanks, ALF. I was pretty suspect of that caliber stamping. I assume the stamping on the left sidewall changed at some point?

The inscriptions and tiles on the sidewalls changed as the name of the company changed. The history of the country and the communist rule influenced the name and title of the company.

The company was State owned but in order to do business in the free world the name and status of the company was changed. We see later the term "Narodni Podnik" used. This translated meant " Peoples enterprize" very much in keeping with the ideal of communism
