1939 MkIV GSR Unusual Configuration

[Bullet]

Hi all,

I've come across this gas mask with strap bag and white/yellow filter canister (elbow outlet), I've not seen them in this configuration. Any ideas who was issued these?

Crap pic! but probably for vehicle use mounted?

Yip.. poor quality pic, can't expect much of a response from it. As soon as the postman drops it off I'll upload better ones. The seller tagged it as a 'Riot Mask'.
