In the above graph, there appear to be two different production periods. Apparently there was a haitus in production starting in about 1917 when production of the Model 1916 started. Production of the Model 1893 resumed in about 1921. Note that there are several "flyers" that don't fir the pattern, but I have presented the data "warts and all".

Carbine data is a lot more scattered than the rifle data above.
Data updated 1/21/11 Apart from a couple of "flyers", the production rate of the Model 1916 is fairly steady and consistent.
