looking for a special hammer for a special person

We are working on a refurbish of a S&W DA 45 for Paco Kelly. It is similar to the model 1917, except some of the parts are different. It is also different from the S&W N frame hammer.


I found a hammer on the internet but it didn't fit so back to square one. If any of you hear of or see a hammer for the S&W DA 45 let me know.
