I for one am relieved that the problem is fixable.
The whole story:
A friend of mine decided to upgrade his field gun and he bought a very used 16 Ga. Parker VH grade (?) on an "O" frame. Before buying he had a gunsmith checkout the gun and discovered that the gun was basically sound, but had been previously restored and needed it again. The smith told him that to restore the gun back to original would cost more than the gun is currently worth. Because the gun felt perfect when my friend mounted and shot it, he bought the gun and sent it to a shop that specialized in annealing and case color hardening. After annealing the gun was sent to an engraver to touch up the minimal engraving which include the name parker that had almost been polished out. The gunsmith that previously advised him, attempted to assemble the action and said that because the action was warped during case color hardening, the hammers would not line up to the firing pins. He is very disheartened and will take the action back to the shop that did the work. The original shop is considered by many to be experts in case coloring and I won't disclose their name until they have an opportunity to fix the problem. The gunsmith is outraged and has said that if things are not made right, he will no longer send them work. Please excuse any misstatements on my part as you are reading this second hand.
I'd seriously question the word of your friend's "gunsmith". Parker hammers have the firing pins cast as part of the hammers. They are not separate parts. Either he does not know what he is talking about or has been misquoted.
