Hallo Eric,
According to John D. Walter, J.M. Eckart Lederwarenfabrik Ulm/Donau was in operation from ca. 1913- 1945.
If you would like to get more on this company I recommend to contact the "Industrie und Handelskammer" (chamber of commerce)in Ulm. May be that their archive has survived WWII.
Concerning the infantry regiment it could be usefully to look in the German Ebay under Regiment or Infanterie Regiment.
There are offered lots of regiment's history books. But in German language.
