I getcha!
I thought you were trying to restore it to as close to original as you could.
Never mind.
There were a lot of M-3 blades sold as surplus, or left over in the factory's when war contracts were canceled suddenly at wars end.
They were advertised as 'hunting knives' in the outdoor magazines into the 1950's for $1.85 + .15 cents postage.
Or something?
For instance, Utica got left holding the bag on a bunch of them when the war ended.
So, they ground the name off the guard, polished the parkerized blade, put a stamped chrome plated sheet metal straight guard on them, and marked them with a lightly etched 'Kutmaster' trade name.
There were also reject blade knives sold commercially by the manufactures during the war with unmarked blades or guards. Usually sold with a plain brown leather sheath.
And some wartime M-3's were reportedly produced with smooth handles.
So who am I to say what it 'should' look like?
PS:
Handle is shorter right at 4" some of the leather washers look real thin maybe a grasping groove gone wrong
I think what probably happened is the end of the tang was broken from pounding with it, or ground or sawed off in front of the pommel to get it apart.
That would shorten the tang & handle washers about the 1/4" yours is missing.
I have a very early KaBar red spacer that would be worth a few more bills if the handle wasn't a 1/4" short for the same reason!
