I would really appreciate any help with a value of a Venom tuned HW77k ( .177 )and period Kasnar scope. I got this a while back from the original owner, who sent if off for a Venom tune, as well as their cocking grip and revised muzzle break/ catch. It is in very good used condition, some odd minor surface marks and shoots very smoothly indeed still. Scope is their 3-9 AO wide angle with the "TV Screen" view, sitting in a 1 piece mount. Venom sticker still looks to be good tucked under the scope. Serial number is 1033560, so about 1986 I think.
It is unfortunately just sitting in the cupboard and I really can't see me getting to enjoy it.

Thanks folks in advance!
