I will definitely check every mark. I have a few that aren't really supposed to exist if you ask the average collector. I really need to get into the bigger books dedicated to the different Japanese bayonet variations. For instance I have a Naval Bowie tip bayonet that looks home made, with rough grinding marks on the tip. I thought it was a fake at first but then when I put it next to a known correct model it was a perfect match to the profile and I got the thing cheaper than it should have been even if it were a known fake. Also have a late war trainer wih straight quillion. thats one out of probably 100 or more trainers I have looked at. I used to love training bayonets until everyone decided they were "RARE AND COLLECTIBLE" and thus worth another $25-$50 over a regular bayonet.
Oh well, I already have my eye on a VERY nice rubberized sheath Special Naval Landing Forces bowie. He wants $350 though. I may have to work a trade or something. Unfortunately he knows how nice it is.
I own firearms not to fight against my government, but to ensure I will not have to.
