12 bore CZ BRNO ZH202 over and under, 26 ins ported barrels, solid rib, 2¾ ins chambers, 14½ ins stock
The ZH Series was introduced in 1958. It’s probably fair to call the design unconventional.
The ZH's were hand made. With that 'hewn from a sold lump' feel Mercedes used to have. Like many BRNO/CZ guns of the period, when compared with the Italians, the finish was a bit ‘wrong side of the iron curtain’, but they have a certain rugged charm. The only plastic is the butt plate, everything else is steel and walnut.
The skeet barrels are 26" with the muzzle ends "flared" into a muzzle brake that looks a bit like the ventilated "cage" on the Cutts Compensator Skeet chokes of the 40’s and 50’s.
The barrels are joined at the cage and the breech, with space between them for the rest of their length. and have fixed skeet chokes, made to cover a 30" circle at 20 yards with a nice, even pattern using most target loads.
There are other shotgun versions; fixed chokes, usually tight and barrels in either 28" or 30" and combination offerings. Durability is an understatement with these guns. The action is made to handle everything from 22 Hornet, and 5.6x52 [I know me neither] to 7mmx57R, and 7x65R. Typically over a 12g, although 16g were also available. The stock came drilled for recoil weights.
A sliding breech block is pushed forward by springs when it is closed, and cams back when opened.
The barrels pivot on trunnions that project out of the sides of the barrel set and engage with slots in the receiver. The fore end is screwed to the barrel set and doesn't get removed during take down.
The two triggers are an interesting set up. Front trigger fires the top barrel only, the back trigger has two functions; 1st pull fires the bottom barrel, 2nd pull fires the top. This is for when you’re using a rifle/shotgun set up, the top barrel being the rifle. The auto safety is in the front of the trigger guard, like a U.S. M1, and set by two independent systems.
The lockup is very strong, the breech system was intended to allow other barrel sets to be matched to the gun with minimum fitting effort by your gunsmith. They are not truly interchangeable but required less fitting when installing a barrel set, than from many contemporary brands.
This one slams shut with a bank-vault clunk and feels ready to do the next 50 years of service.
