U.S. M1 Carbine
Quality H.M.C.
Serial Number: 1,638,442

Industrial Police
Justice Police


On the top of the recoil plate of this carbine are the markings HE-J.P.. One source indicates this was the Hessen Industrial Police but it may have been the Hessen Justice Administration's prison police. The Hessen Industrial Police operated under the command of the U.S. Army Military Police. Elsewhere in the American Occupation sectors the Industrial Police who were issued carbines did not receive them from the Office of Military Government. They were the property of the U.S. Military Police. Refer to the web page for the West German Labor Service and the web page for the Hessen Police.

This carbine is located in New Zealand and most likely traveled there by means of a small arms import/export firm. Unlike the U.S.A., New Zealand does not require the importer to place their name on the small arms they import.
