I’ve passed on a few good one for sure; Diana 54, Webley tracker walnut stock, HW97 K .20 cal, Feinwerkbau 102, crosman 6500 (Anschutz 335) but the one I regret the most was a Feinwerkbau 300s universal in perfect walnut left hand stock that I sold for a friend. I wanted that rifle so badly but it was just not a good time for me financially. I still talk to the current owner once a year or so. He is still on an airgun forum I frequent. I hope to buy it from him some day. Packing that rifle up and shipping it off was a real kick in the pants. Don’t get me wrong, I don’t want to sound whiny! I recovered from that crappy time. I have more rifles then I need But that feinwerkbau still haunts me a fair bit.
