looks like the replaced hammers were from a much lower grade gun. The replacements are much more appropriate.
Chuck, I don't think there is an axle-to-firing pin difference.

In both pics the hammers look the same to me. What am I missing?

1. Before, the gun as it was when I bought it.
2. After, the gun with the donor “D” grade hammers.

For funsies, here is the donor gun, wearing its “new” hammers!!,

I’m going to have this gun put back on face, have the barrels refinished, and let Dave Wolf do his magic refreshing the stock, then let the new owner (TBD) go off on his own hammer search!!,

Does the faces of the hammers contact the firing pins properly?

I have several guns with hammers that do not look like they will work but do so very well, Gary

yes Chuck, they do vertically.....I am not a geometry expert, but as the hammer face approaches the firing pin, it very quickly squares up with the face of the firing pin. The hammers do need to be fitted a little closer to the frame of the gun, but the firing pins still are adequately struck as is. I am going to completely refresh this gun, so the Gunsmith chosen can get that accomplished for me.

VERY NICE!!!

I've seen hammer guns with cracked hammers and those with obvious replacement hammers so I assumed that the originals were either lost or broke from hard use.

The before and after pics of my early lifter are also a testament to what frontier pads, ballistol and elbow grease can accomplish!
