Your Krag, #194608, would have been assembled around April, 1899, as a U.S. model 1898 rifle.
The Stock is a cut-down rifle stock. It has a patch on the forearm tip, filling the lightening-channel, that was exposed when it was cut.
Your stock has been recycled a couple of times. It has three 'Proof" stamps. The foremost "Circled - Script P" was stamped when the Krag it was on was function tested for acceptance. The second "Circled - Script P" was applied when the stock was re-used on a Krag undergoing rebuilding. The plain "P" was applied over the original stamp, when a Krag was again subjected to function testing, likely around WW1.
Your Stock 'Cartouche' Has the letters "J.S.A." above a date. This stands for Joseph Sumner Adams, the shop foreman, where the acceptance inspections were done. I cannot make out the date.
You mentioned, your stock is marked with a "CA". I think, I can just see the edge of an "A" in one of your photos.
Frank Mallory wrote, (in "The Krag Rifle Story"), that around 1908, letters started being stamped on Krag stocks to identify the facility that had done cleaning and repair work.
BTW - Krags were in U.S. Service and National Guard use from 1894 to about 1919. Krag rifles remained even later on U.S. Ships. By WW1, the Army had relegated Krags to 'Training' use or secondary service. A lot of Krags were 'refurbished', during their service time. During the process, rifles were taken apart, parts were checked, refinished, and put together in new combinations of parts.
Something else to note: Your hand-guard appears to be of Italian walnut (which the U.S. used on some Krags). The hand-guard is the correct type for the model 1901 sight, that you have. However, the hand-guard has been 'stepped' for the 'sight-lever'. This should not be necessary, but, for some reason, your rear-sight sits LOW.
I wonder if your Krag has a replacement barrel, possibly made from a 1903 Springfield barrel?
