Off Topic: WWI German Helmet Question

[Carter]

I didn't notice it with any of the gear on display in this thread, but something that was particular to a lot of the gear used during WW I and resurfaced just prior to the 1st Gulf war was the marking of not only the year of manufacture, but also the month. For example, I've had M1910 haversacks that were dated "June 1918" or grenade vests dated October 1918.

I have noticed that also but this haversack is only marked R.I.A. 1916 and one of the first aid pouches is marked like this: R.I.A. 1910 with a capitol M centered below the RIA stamp. March? May ?
