recently found this strange double darby type handcuff in the UK. It didn't come with a key, but one from a (non-regular) darby fit.
Has anyone seen this type before? There is a backstrap element. I used some WD 40, but haven't cleaned them up much otherwise. It works fine.
I'll try hosting pics with my e-mail provider, we'll see if it works. The link is safe, I haven't found out if I can embed the photos directly here. Joe, if you can do it, be my guest.
Have a nice weekend!
