Thanks, it is owned by an individual according to the list of « Death from above »
I notice that it also has a serial number on the trigger block: not always the case, but I don’t know why.
This one at the JM Davis arms museum in oklahoma has a type 1 that does not have the grenade sight notch, but does have the extended trigger guard. Unfortunately I haven’t been able to find a good picture online to see its serial number. This is a photo a friend took a couple years ago.
Got some info from Ian at forgottenweapons and 3 of the 4 that he has photos/video of are already mentioned here. Serial number 141 is a new one that I haven’t seen mentioned, that one has the grenade sight notch and standard trigger guard.
