[easterneagle87]

Got these in a group lot. Nice pair of USMC EGA cuff links.

 

Whose maker mark is stamped on the side?

Any one?

 

It is a tough one: I think cufflinks were mostly made by costume jewelry makers, not the same makers who produced metal insignia, so cufflink makers are not something too many collectors would have noticed - but of course, when I say something like that some forum member always jumps in with the needed info

Here's a better shot of the mark. With the configuration/shape of the EGA's any idea how old they may be?

EGAs on home front aren't the best indicator of age as jewelry firms often were behind the times in patterns. That said, the emblem is very WWI-esque, but I would estimate the links around WWII
