I like Full Target 6" for a revolver like that.
Here's what I would be looking for.
Target Trigger
Target Hammer
Target Sights
Target Stocks
17-3 is a good generation
You can still find a pristine 17-3
Hard to find anything older that is "pristine".
I found one (K-22) in January for $785
S&W 6" BLUE K-22 MASTERPIECE MODEL 17-3 GONCALO ALVES CHECKERED TARGETS .22
Completed my trifecta :
K-22
K-38
K-44 (Model 24)
There was also a K-32 in 32 S&W Long. I've shot one, never owned one though.
