Depending on the condition and if it works, they usually go $55-60. Unless this one has a box or something offer him $60.
I have a pretty nice ZVP that I resprung with a new spring (Just to be sure I had full power) Yes they shoot high @ 10m but are capable of some very long shots and that's where these big old pistols shine! 20-25 yard sodacans are easyhits!
They are a "sort of" copy of the old Diana model 3 done by the Czhec's and are very well built. All steel and wood and look at the wide steel trigger! Jus a fine old airpistol that'll last forever (leather seals). Dependable as a clawhammer! A nice add to anyones pistol collection.
