(sorry for this odd closeup, wanted to get an image of the top vent for everyone, its a single hole like on an M15 rather than the several hole vent design on the M26)
Above is an Adrian I picked up over a year ago. It is very clearly not an M15, and it is clearly not an M26; so I am a bit confused by it. Was wondering if anyone here has any advice on it. Has some hand writing on the inside of the liner that I can't make out, something like "Sopsto Fyoet" though that is unimportant to its identification.
Thanks in advance!
