Just brought it home, looks like it may never have been fired till today.... Came with 3 mags, I got it for $300..... good? bad? fair? It shoots great!!
If it's not been bubba'd, you got a great deal --- Vz 52/57s with one mag usually run $550+. Corwin Arms recently brought in some spare mags, but until then, spare mags were hard to find and pricey.
Check your serial numbers to see if they all match: left side of buttstock, inside of front handguard, oprod (sheet metal under handguard), receiver, bolt, bolt carrier.
There aren't many fully-matching Vz 52/57's --- usually at least the front handguard is mismatched.
Also, check the buttstock compartment to see if you have the full cleaning kit, including the carbon scraper.
Enjoy your rifle, and remember, if you shoot corrosive, make sure the area under the piston/gas port is well-cleaned as I've seen a number that have seized due to rust.
Here's a picture of my Vz52/57 sniper w/ side rail and Czech NSP2 active IR night vision scope:
