Second grandfathers Bayonet ID

[jmurphy]

Ok so here is the second one. Total length is 20 inches with a blade of 16 inches. Has two marks on the blade and a 5 on the gaurd. So who is the maker and when was it made and for what and what does the 5 mean.The marks look like a J in a circle and a C in a circle.
Thanks again

Not sure. Could belong to one of the Mauser variants, however does not appear to be a 3rd Reich bayo. You may want to also post them in the Bayonets and Trench Knives of the World section to double your efforts. Same goes for the others you posted.
