Old Smithy's website is back up. I didn't find a good match. The Chinese bayonet is the tri-form type, the handle looks exactly the same with the exception of the two small rivets which are larger on mine. Could only find one ersatz Germanicon bayonet on his site, that being the crank style I believe they are called.

Debating whether I want to head out to a flea market today or just relax for the holiday.
