Just scored this minty Crosman 150 for a really nice price on eBay.
Thanks for the info if it does need a reseal. Will definitely check out vids before any disassembly.CT,
Thought my 157 was clean, that looks un-used! Crosman re-sealed mine first time, I did it next. Use polyurethane "O" rings, the black rubber ones dry out too quick. Ring kits were on eBay, poly rings are twice the price but worth it. An older guy has a re-seal video that's very helpful, there's a trick to it, watch video first. The short pin removal, mentioned by ChrisS, sounds right. Great sense of satisfaction at re-seal completion. Very nice score, sir. WM
