Joe -Thanks for the picture - it's worth a thousand words!

Looking at the pin, the "F" leans slightly to the left, and the drooping lip on the top right end of the bar is barely visible. Center bar is in the same place but is equal on both sides. The "C" is the same right down to the small lip on top. But there is no "L" or circle.

I'm comfortable with Franke & Co. since the designs are really very close. It is probably just a trade mark variation, possibly because of the small available size area on the bottom of the pin.

Thanks again, Dan
