The action is based on Perks patents of 1878 and 1886. Scott used this action on side lock guns made between 1890 and 1897. The action features cocking rods retained by screws in the water table.
From 1898 to 1935 the Perks action was replaced by the Rogers patent action of 1881.This info; was obtained direct from Scott,s management in 1984.
For many years I shot a; Scott Monte Carlo "B" #51173 [ Made 1893] that was built on the Perks patent. It was exactly as seen in the photo,s. I had absolutely no problems with the action.
