Zonie, if this post is in the wrong spot or incorrect format let me know and I will have you delete it and I can redo it. I had several of the identical item and wasn't sure if I should post them all separately or as one ad. I have a few NIB Pietta 1851 Navy Yank .44 cal spare cylinders available. I was going to use them on my 51 .44 cal as spares on the bench or to carry in belt pouches but have sold the revolver that they fit so I don't need them now. These are a drop in for the Pietta 51 yanks in .44 cal either the full length barrel or the Avenging Angel style snubbies. They will NOT fit Euroarms but should be OK in Traditions. If in doubt measure the overall length of your cyl and I'll put a digital caliper on one to see. They have the safety pins on the back and all have a full set of nipples. I've bought new cylinders before and had to buy nipples on top of that. I would like $50 each plus shipping which is about half of what they sell for when you can find them. I can do Paypal plus the fees as a discreet transaction or I take US Postal Money Orders. If you need information let me know by post, message, or email and I'll help you the best that I can.
