Slavia pellet gun info request

Nearly 40 years ago I recivied a pellet gun for Christmas. It was bought at a small hardware store in Middle Georgia. It is a Slavia ZVP with a serial number on the side of 12441. It was made in Czechoslovakia. It has a number on the top PIC # 616. I was interested in the history of the gun and how much it might be worth. It is in good shape. It is a wooden handle and iside the barrel is rifling. Thanks
