Welcome to this great hobby! I am glad that you found this site, your fellow oldgassers are glad too!! Do you have any pictures of this pump? The cylinder shouldn't be a problem, there are enough companies that offer repro cylinders I can assure you one can fix you up. So far as the skins go, I'm not sure if anyone offers what you need but if you'll post some pictures (or e-mail them to me at haninfrared@msn.com) I will post them. I and others may have some ideas to help with this skin problem (no pun intended- ha ha).
Welcome to the hobby and the site, WE ARE GLAD TO HAVE YOU!
