Rory, the short rifle morphed into the 99C (solid frame) and 99D (takedown). These had the rifle weight barrels. the 1899H (lightweight) morphed into the 99E (solid frame) and 99F (takedown). Both had the lightweight barrels until 1926. With the advent of the medium weight barrel in 1926 the 99C and 99D ended and the 99E and 99F continued with the new medium weight barrels. This was the end of the rifle weight barrels and the lightweight barrels. The only difference between the C and the E and between the D and the F were the different barrels. There was no need to continue with the C and D since they would have been the same rifle as the E and F.
I'm going to need to read that when I'm not so tired. Good info.
