Dear Mr. Daniels,
Thank you for posting your request on History Hub!
While the National Archives does not have records about the service history of individual firearms, there may be records about the manufacture of that model of firearm. We searched the National Archives Catalog and located 8 file units, 1 series, and 1 item related to Springfield 1898 in the Records of the Office of the Chief of Ordnance (Record Group 156) that may contain some relevant information. We also located 23 series of records from 1890-1910 in Record Group 156 that were created by the War Department. Chief of Ordnance. Springfield Armory that might be of interest to you. Some of these records have been digitized and are available online using the Catalog. For information about the non-digitized records, please contact the National Archives at Boston (RE-BO) at email@example.com.
Plus, there are several additional History Hub discussions related to the Springfield Armory that you may wish to review.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RE-BO. We apologize for this inconvenience and appreciate your understanding and patience.
Next, the Springfield Armory National Historic Site (US National Park Service) provides some information online. We suggest that you contact them directly for further assistance.
Further, we located several Springfield Research Service Books using WorldCat.org that might include additional information about your specific weapon.
Finally, the Smithsonian’s National Museum of American History has some online information about the Springfield Armory Model 1898 Krag-Jorgensen Bolt Action Rifle that might also be of interest to you.
We hope this is helpful. Best of luck with your research!
In regard to your M1898 Springfield Krag rifle. It was manufactured in 1900, the production started that year with serial number 250000 and ended with serial number 305999. Unfortunately I could not find any serial numbers in the 4 volumes I have of the Springfield Research Service books in the 265000 range. And the ones I found in the 264,000 range or 266,000 range are to wildly different groups/units so nothing which might help you figure out the source of your Krag.
