McCandless thanks for responding.
The top of the lever is reprofiled back to create the short stroke.
The Cody SS is about equivalent to a 3rd gen from Pioneer.
If Boomstick Arms is still in business they can convert Ruger 38s to 38-40. Had a pair done about 4 years ago. Cost including the revolver was $1,300 each.
For 38-40 like this brace of Colts - shoot them once per year.
