I used to own one. The number after the dash is the year of manufacture. I have this this bit of info on one that was offered on Gunbroker a few years ago:

Česká zbrojovka a.s., Uherský Brod, (CZUB), is a firearms manufacturer established in 1936 in the small Moravian town in the Czech Republic. After World War II all the firearms manufacturers were managed by a single central agency which required that "Any firearm exported will bare the BRNO markings", this is why there are a great deal of CZ Uhersky Brod firearms with BRNO markings.
Throughout the Cold War CZ manufactured a wide variety of military small arms including the CZ 52 pistol, the CZ 58 assault rifle, the vz. 61 Škorpion, various .22 caliber training and target rifles and of course the CZ 75 family of pistols.
In 1991 the Czech weapons factories were "de-centralized" and began business as free market companies. CZUB was the first to move into the free world economy, establishing a small arms presence across the globe and dominating the market in over 60 countries.
In 1991 CZUB established a permanent presence in the United States with the founding of CZ-USA. CZUB and CZ-USA continue to expand and dominate the small arms market world wide, with military, police, defensive, sporting and recreational firearms of unparalleled design and quality.
The CZ factory employs some 2000+ highly trained engineers, craftsmen and business personnel, making it one of the largest firearms manufacturers in the world.

Barrels are forged chopper lumps with third upper bite (Purdey design) made of Poldi electro steel, silver brazed with solid concave rib 28.3” (720mm) in length choked modified and improved. Actual stamping on the bottom of barrels reads: 17.6 diameter on left and 17.8 on right, then both barrels have 18.35 diameter throats, obviously in millimeters. Czech required proof mark is stamped –95, which means gun was made in 1995. Production ceased in 1998. Chambers are 2. ¾” and fitted with selective ejectors (fired shell eject, unfired extract). Ejectors are operated by Anson & Deeley type splinter forend latch. Action is of true sidelock with etched game scenes finished in silver, complimented with cocking indicators and automatic safety on upper tang. Double triggers, oval cheekpiece, LOP 14.1/4”, Turkish walnut, recoil pad. In fact this model was the only gun, that Brno factory never made any profit on. Its production was staggeringly expensive and required a small group of craftsmen to hand fit all those machined pieces together. Interestingly, Brno Arms was the largest small arms production in the world in early 60s, having about 10000 employees. Yet, only a few hundred of SxS were produced yearly. They are history now, Brno production buildings are empty and turned into warehouses. For those who wonder what designation Brno ZP149 means, it goes like this: Brno – city and manufacturer place in Czech republic, Z – zbrojovka (weaponry/ armament), P – Pavlicek (name of designer), 149 – first introduced in 1949.
