Hi folks, Picked up two Japanese bayonets - one with a frog. The one with the curved quillon appears to be earlier and the other a later model. I'm new to Japanese collecting and would kindly accept any comments on these examples. I paid $140 for the older and $125 for the later model with frog. I'm guessing the price for the older one was a little high and older example was in the bargain area. Neil H.
