HELP Identifying Single Action Hammer

[Ruger 10/22]

I need help identifying a single action hammer that came in a parts package
I do know the one spur less hammer is for a Ruger SP101 DAO but the single action hammer has me stumped as I have only had one single action revolver in my life which was a Virginian Dragoon 22 Magnum in the early 90s = 30 years ago now
Thought maybe I could post the photos at a few forums & come up with something
Don't know if it's Ruger Colt OR??~~~~

As I said I know the one above is for a Ruger SP101 made before they where cast or MIM, It is the reason I ordered the parts package & ended up with the SA hammer which was also listed as for a SP101s but knew it was wrong from this photo

I have now been told the SA Hammer is a Ruger New Model Blackhawk of one caliber or another

Once I got Iowegan to identify it, I knew & looked it up & found several like it to study on eBay & Gunbroker
It for sure is the Blackhawk NEW Model as it has a transfer bar cut
Thanks to everyone
The hammer is for sale but can't post it for sale here until I get 50 quality posts
Might just keep it & buy a BH to go with it
The shop up the street has a NM SBH but wants $899 for it WOW!
