German M-42 Helmet w/ personal ID markings: Need Help

[esquire93]

Have German M42 combat helmet (Luftwaffe I believe) that has thick gray camo paint on the exterior and chickenwire added. Leather liner is inked with a stamp, not hand written. The stamp, in black, reads:
"Lw.-H. Freise, L. 54382, Lg. P. A. Munster". I would like to research this helmet, so any help is appreciated.

Thanks...
