That's the problem.  You would have to dive in full time in the Springfield Armory's records if they exist regarding the Krag production.  Or you would have to live in the National Archive for twenty years going through the microfilm or the original books and reports.  Or you would have to spend time praying that Archive.org or Google Books or whomever else digitalized the above sources and pray that you get lucky finding production documents that were probably purged in the 1950s.

I think the best we can do is the census and making KCA the premier Krag site. 

By the way.  Where do we get the European Krag production records?  Maybe KCA Detachment 1?
