This is a German ammo pouch with markings to 124th Regiment.

One of the closure straps has broken but the end was found tucked inside the pouch!

There is an internal division for the cartridges, its made of some sort of hide.

Only example I've ever seen.

This is a brass 37mm case (fired) dated Aug 1918. The ‘bullet’ itself is steel with a single (unfired) copper driving band. The bullet has a green painted tip, quite faint now, but this denotes DAY TRACER. Unusual to find a German 37mm as they are usually French. Excellent condition and not a ‘dug up’.
