Rear Axle Strange Marking
 

Found this on the RIGHT (Small end) end of a rear toggle axle pin on a 1914 Erfurt LP08? Looks like a TR Eagle over an "H" followed by two numbers or letters? Sorry about the picture, I havent figured out how to use this camera yet.
Thanks for any insight on it!http://members.rennlist.com/lugerman/MMAxle.JPG
