Looking for Hiatt darby non-adjustable cuffs

I'm currently looking for a nice pair of Hiatt darbies with original key, circa 1800's. There was a nice pair on Ebay that I missed out on by 1 dollar.

If anyone might have a pair of Hiatts or other 1800 era fixed cuffs they'd like to sell, I'd offer a good price.

Thank you
