I have restored a few snorkel pens and I really like working on them (so far just about everything from an admiral to a sentinel and many in between) but I have no more of my own to restore. If anyone has any snorkels that they would like to get cleaned up and working I would like to do it for you without any charge for labor. You pay shipping both ways plus 5 dollars for new parts. I will install a new sac, a new point holder gasket, a new o-ring, applying pure silicone grease and talc the sac as well lightly polishing cap/barrel if needed. There is no profit in this for me other than the experience. If you have a badly damaged pen or one that is missing parts then I'm afraid I can't help you.....refurbishment only.

PM me if you are interested.
