Tenax Rolled Gold (backs) cufflinks Patent no 355441 1930s Made in England
* The Invention: A spring-loaded mechanism featuring a chain connecting the front and back of the cufflink. The chain pulls out to expand, letting the wearer pull their shirt sleeves up their forearms without undoing the cuff, and then retracts back into a bullet or torpedo-shaped shell.
* Origin: Stamped "Made in England" and "Reg. Patent 355441". They are highly collectible pieces of 1930s-era men's formal dress hardware.
