I've picked up 2 bayonets at a sale and after diving down the rabbithole of bayonet research i'm a little stumped. The first one i think is a Model S84/98nA mauser bayonet marked with Rich. A Herder Solingen (see pics) but i'm struggling to get a date as the info i'm finding and the stamp on the top of the blade don't seem to tie up. I'm wondering if this is quite an old bayonet due to the crown stamps? As for the second one i can find no marks other than a serial number on the hilt and the design seems common across a number of nations - it's a little shorter than the other and is double edged. I'm not sure this one is german as some swiss made ones i've seen seem similar. So i'm a bit stuck and wondered if anyone with expertise in the area could offer up some more info on them? I'm interested mainly in dating them and confirming country of origin. Thanks guys!
