Here is a nice example of Romer handcuffs. The price is most interesting.
This set of handcuffs had a high bid of $1,391 (Plus $7 Shipping).This auction is for an original set of Romer Handcuffs. Patented April 7, 1880 and made in Newark, N.J. No key. These seem to be a very large size handcuff, I can slip them over my wrists. Measures 10-5/8" long and the cuffs have a 3" inside diameter measurement. This is the type and style that would have been carried by old west sheriffs. Excellent condition with great untouched old patina!! Fresh from an estate. See Pics. - eBay (2 Apr 2012)
