Help with Equipment Provenance - All Arms Training School

I have an M1934 Stahlhelm Civic Fire Police German Helmet (as pictured below).
I am fairly certain this is a post war production item as it has no manufacturing stamps inside the shell and the liner has holes perforated in the front - all indicators apparently.



For me, the interesting part is the use of the helmet itself. The decal on the left side is BAOR All Arms Training School - at least that's what research has told me so far. I would love to find out more, and naturally, this seemed the right place to make enquiries. I would be very grateful to understand what units may have used such equipment, where they were based, what year(s) of use may be likely, what exercises and duties may be have been performed etc. Oh, and if you had the initials HH and can recall using such a helmet (size 57), this may have been yours!
Apologies if this post seems naive - I am just beginning my journey in this space...
Many thanks
Gareth

Maybe a 'Fire Helmet'?

I seem to remember in the 50's that the locally employed fire crews were equiped with old German helmet as used by the local fire brigades. Later when the Army Fire Service modernised they were equiped with Brit kit.

The logo ( Badge was in use at AATC from 1946 to 1950).  The early fire fighting crews came from Range Wardens - there were more than 360 of them on the sennelager range, they had a second hand half-track as a fire fighting vehicle - it could get to most places through brush, and water logged ground.  Main  fire fighting eqpt was a long handled springy steel-tined beater which was very effective  (the early post war landed gentry took examples back to the highlands for  use where the grouse grow).  Many of the Range Wardens were members of  Feuerwehr in the villages around the Trg Area and doubtless adapted what ever was found useful - including part worn helmets.  The worst economy drive (in recent years) was to stop buying the steel beaters and providing, instead, an item with a UK NATO Stock No which resembled a length of redundant water hose on the end of the stout ash stick - spread the flagration better than a wwest wind.
