This looks very similar to a ww2 bayonet I have for the k98. Are you sure it isn't from ww2? I thought, that the ww1 Gew98 bayonets were the "butcher" blade/sawback types. Then again, I could be wrong.Nice WW1 german S-84/98,Mellich is a harder mfg to find.You have a nice clear mfg stamp on this one.This bayonet is getting hard to find.This mfg had slightly diifferent blood grooves than the other mfgs.I think 60.00 is a good price even back then.On ebay these WW1 bayonets go from 95 to 150.00 depending on if someone overseas is bidding on it.On ebay the prices can go quite high depending on bidder
