I wrote a three-part article for the IAA Journal on various connections between the Maxim Cartridge Company, the J.B. Wise Ammunition Company, and the U.S.C.Co. The section on Maxim is in IAA Journal Issue 493, Sep/Oct 2013, with the discussion of the M M C 1916 and M M C 1917 8 x 58R Danish Krag on pages 22 and 31.
Bear in mind this was an ammunition article on three specific companies, so there is no discussion of Danish Model 1889 Rifles, nor of the transfer of the Danish Contract. I know little or nothing about either, and they were outside of the scope of the article. Further, in my research for this article, I found no particular mention of bad quality from Maxim, although that perhaps in not surprising. They did have problems during the short time they were making ammunition. At any rate, that particular information is not covered.
