Hi
I believe Stan does have a picture of of this cuff on his DVD....a picture of mine.
Mine was originally sold to a guy in Michigan (not a cuff collector) on ebay a few years ago and I coincidentally met him when I went back there a couple of years ago. I finally got it from him about a year and a half ago. He bought it from a guy in France. I date it to the turn of the last century to the 20's.
The one for sale is a bit more robust than mine and I am crazy about what I believe is the original key. My key is nice, but definitely not original. The patina on mine is much nicer. I do not know much more about it.
