Vintage circa 1960's offers men's removable dice gold plated cufflinks, unknown maker not marked, have four leaf clover designs

Aquired these oddly enough from a gentleman who was a retired Pastor of all things. They are fairly rare and aren't marked with a maker or metal content. It might be gold plated but could be brass, the metal doesn't attract a magnet. I've heard these were made in Austria offers but no confirmation. What I do know about these is that they are pretty cool. If for some reason you were out on the town dressed up with your French cuffs and wanted to shoot dice you're all set! Must be lucky cuff links too as they have applied four leaf clovers on them as well. Nice pair.
