Identified Officer WW1French ARS Gas Mask W/Aluminum Can & Straps / German use?

Description

Identified Officer WW1French ARS Gas Mask  W/Aluminum Can & Straps /  possible German use? Very nice complete French Gas Mask sets are difficult to find these days. The masks are usually missing from these cans because the aged poorly and became as hard as a rock and people threw them out. The condition is typical and hard. Can and straps are fantastic showing use but no abuse.  This mask can is ID to a Captain, but oddly the mask is marked through a German depot. I am speculating when I say that the Germans might have captured this Officer or stores of masks and reissued to reserve or landwher units. Questions are welcome.
Condition is Used. Shipped with USPS Priority Mail.
