Translation Help Please Ink Stamp M35 DD Military Police Helmet

[Chris Lee]

Folks,
I was offered a DD M35 military police helmet with an ink stamp on the inside of the helmet. I`m not a helmet guy but a friend who is says it looks all good, however, there is an ink stamp on the inside of the helmet that I would like to know what it is. I`m unable to post pictures but I`ll do the best I can . Some of the lettering is blurred and i can`t make out the letters, so here it is as follows:

Abgenommen
IV
1938
Besenaffungsamt
For Heer U. Marine
Any help would be greatly appreciated and thanks.

Sounds normal a lot of helmets have this sort of stamp to the inside at the top . However of course there are new stamps that fakers use to jazz up helmets . Rob
