I just purchased my first SxS. I don't know much about shotguns so any info is appreciated, here's what I know:

CZ ZP-47
12 Gauge
2 3/4"
Made in 1977

Barrels say "Special Poldi Elektro" Like the Brno Shotguns

One barrel says "CHOKE 17.6" and the other "CHOKE 17.8" Why two different size chokes?

Previous owner states only 10 rounds though it, and it looks it. Everything is tight, fit and finish are (IMO) Very good, but I'm no expert.

The gun doesn't have an ounce of rust, what looks like rust is just the grease, I haven't had a chance to clean and shoot it yet.

And it came in a cool case, not sure if its a factory case, but it fits. Case is a bit worse for wear, but it works.

Other than that...not really sure
