thank you for all that information, fascinating stuff. I've measured the muzzle ring countless times now but it still appears to be 15mm in my reckoning. Does that change anything?

A normal P1888 bayonet would have a 16.5mm MRD so the smaller size would lead me to believe that my 2 "guesstimations" above may be on the right track.
