Hi, a nice sounding rifle . Yes the .177 is the rarer more collectable caliber, but given events on here this week am reluctant to start offering Airsporter price advice (have a search in this section ). Ha ha ha. If in vgc you are looking iro £175 plus post. If boxed and mint a little more, but if not quite worthy of the word "very" before "good condition", less (obviously) on a condition related sliding scale of value. Pictures will help with a more accurate valuation however, so see if you can post some . Atb: Gareth W-B.
