Vintage stamped number key necklace, salvaged from an abandoned asylum’s key shop prior to demolition.

Left: Russwin, stamped with numbers. Right: an uncut Sargent key, stamped with “Patented Feb 10th, 1891” (this is not the date of the key, just the date Sargent patented that style)

I have a few of each of these keys so the key you get may have different numbers but will be the same style/brand of key.

Chain is close-linked and can be 18 or 30 inches long. The 30-inch chain has no clasp (closed with a small link) and the 18-inch chain has a sturdy lobster clasp.
