You can use any Kit Gun rim fire hammer (flat face) up to 1953 w/o modification. They all used the leaf mainspring.
The 22/32 I frame hammer of course is a rim fire hammer with the firing pin mounted in the frame, and very hard to find. However, the lock work is identical to a .32 and .38 S&W I frame Hand Ejector 3rd Model all the way up to 1953. They were made in much greater numbers than the 22/32 Heavy Frame Target and Kit Gun. So the hammers are much easier to find: on this forum in the classifieds section, e-bay and Gunbroker.
Although these have hammer mounted firing pins, they make excellent permanent or temporary replacements by grinding off the firing pin (which leaves a piece to fill the slot) or punching out the firing pin rivet to remove and use as is. In addition, after grinding or removing the firing pin, grind the small face of the hammer slightly to match the angle of your original RF hammer.

They will work perfectly in the rim fire gun. It will have the rivet hole in the side that can be left as is or filled with a solid pin, and hardly show. It'll have a proper length spur for cocking and shooting.
Or:
The spur of a center fire hammer can be easily transplanted and tig welded to yours.
Or:
One other thought, if you find the same model as yours that's a real cheap clunker but with a good hammer, you could swap hammers and resell the clunker with your hammer or a centerfire replacement hammer.
