The majority of guns were .22 short then .22 Winchester Rim Fire and the fewest in .22 LR. Because the cartridge carrier was only set up for 1 cartridge they are not interchangeable. The later designs included a stop on the end of the carrier allowing the use of S-L-LR . The WRF is similar in size to the .22 Magnum Rim Fire but not interchangeable and quite a bit les powerful. They made take downs and solid frames. My gun was my Grandfather's. He died in the flu epidemic of 1918. Mine was re-barreled to LR. As for original finishes I'm really not sure. They were used a lot in shooting galleries.
