Thank you for posting the additional pictures. The CT., U.S.A. in the rib legend means 1919 or later and the fact that there is no PARKER BROS. OVERLOAD PROVED stamps on the barrel flats --

means the new barrels are from before 1926. I have a gun that got a set of barrels in that same time frame and unfortunately there were no surviving records to confirm the installation. My barrels have a number stamped on the left barrel flat --

Is there a number in that location on your barrels?

A 2 frame 20 has got to be pretty rare.
