KRAG-JORGENSON .30-40 rifle issued to rural bank guards

[lacenter]

I know that this group is about revolvers, but it was recommended that I ask my question here, so here goes.
The paragraph below was on the website listed below. Can you tell me who might maintain records about which banks were issued which rifles (serial numbers) – US Treasury, NARA or some other facility?

"After the adoption of the M1903, the Krag continued to soldier on as a training rifle and in the hands of National Guard troops until after World War I. During the 1930s, the Krag was also issued by the U.S. Treasury Department to rural bank guards to help defend the bank against criminals and was issued to security guards who guarded strategic production plants during World War II."
