Please don't quote me on this but it seems like Mark Parker just had something similar in one of his columns and it had something to do with Fu Manchu, sorry for the vagaries on this, maybe check some of his recent past columns, good luck and HH, neat find!

Tattooguy67 is right. The September 2009 issue of W&E Treasures, Page 14:
"This design is often described as "Fu Manchu in Stocks" or "...in Chains." ....Cufflinks of identical design, but with bar-type attachments on the back, were made by the Hickok Mfg. Co. of Rochester, NY."
I hope this helps.
Happy Hunting!
