Mark there are some on gunbroker. You will have to turn the rim thickness and diameter down about twenty thousanths or till they fit your chambers as they are actually 14 1/2 gauge. I have 20. 28 14, 16, 12 and enjoy shooting all of them but get the most satisfaction from the 14's. Collectability can be argued but the proof is in the shooting. A 14 on a one frame with long barrels swings sweet and you don't have to loan shells to your friends. The thin walled hulls will actually take modern 12 gauge wads if you shoot nitro. The top wads are 13 ga.
