I know very little of restraint history. I have a pair of what I've seen described as "Flexables" in an srticle by Inspecter Maurice. They appear to be quit well made. Near one hinge is stamped (H.M. Dartmoore. P.)but it doesn't appear to me to be a manufacturer's name. The other hinge has an (80) with an arrow pointing toward the key hole. The flat round end opposite the hinge is stamped (R.C.S.) near the center with the same arrow pointing up to it. On the other there is a (3) stamped low center. both have little crows feet shaped marks arround the edges. Can someone tell me if these are reproductions and / or what all that means. Rusty
The Dartmoor markings are somewhat of a unknown. I have a couple of these and have seen two or three others. The marking is always across the outside of the hinge and is a post manufacturing stamp. The cuffs I have seen have been Hiatts or Fields. This is the first I have heard of a RCS cuffs with the mark.
The marking goes back at least 30 years. If you look at the original book on the Stanly Smyth collection (the big blue one) you can see a nice drawing of a Darby with the mark.
I don't know who put the marks on, but they all look the same and likely have the same source.
Take your pick:
a. The markings are authentic and were applied at Darmoor.
b. The markings were applied by an overly enthusiastic dealer
several decades ago.
c. The markings were applied by an overly enthusiastic collector
several decades ago.
I have always considered choice b to be the most likely answer, but I would like it to be choice a.
I doubt that the markings would have been applied by any manufacturer so I don't think RCS would have applied the mark to a cuff.
If anyone knows more I would be glad to hear about it.
