Richard (and Denny),
Thanks for posting the pictures. I haven't done any enhancements yet, but the second from the top I'm not sure about. With the rest looking OK at first glance.
Andy,
You may have some information that I don't have access to, but when I look at the juncture of this rivet to the adjoining crossguard. From what I am seeing it looks like it's filled in with something like a gray phosphate finish. With the bayonet being a wartime example from Bystrica.
Regards to All, FP
