As a pinned and recessed gun it is old enough. The trigger and hammer look new. A built PPC gun would have a finely polished trigger with a stop. Stop could be internal but the trigger is not modified as a PPC gun typically was. Open the cylinder and see if a spring loaded steel ball has been built into the crane. Fits into a little recess in the frame to help lock it in place. Trigger and hammer look new.

Joe S. you said you adjusted the front sight to 50 yards and your shots hit the dirt. Some PPC guns were sighted in so that the point of aim on a 50 yard B27 target was the junction of the head and neck. The point of impact was the x ring several inches lower. This setup was because the neck/head junction is a much finer aiming point than center mass where the x ring is located. Just a guess, but your match gun may have been sighted in for a 50 yard neck hold.
Joe.... your photos explain the mechanism. Screws provide fixed adjustment at each distance.
The sheet steel tab behind the trigger is a TRIGGER STOP, introduced on K-frames after WW II. Secured by a small screw. Sideplate is removed to adjust or check tightness. A loose trigger stop can swing down and block the trigger from a full pull to release hammer. You don’t want that to happen when the Axe Murderer climbs in your window.
Good place for LocTite.
S&W replaced the tab with a steel rod in the REBOUND SLIDE SPRING. Better arrangement. David Bradshaw
Looks like it was once a purpose built PPC gun. The trigger stop in the picture was the common stop seen in the more refined S&W revolvers of the time. Betting the trigger stop screw in the trigger went when the hammer and trigger were replaced.
