Cuff of the Day for March 30.

OK everyone.  We are all at home polishing our cuffs while waiting until the virus is gone.
I want everyone to post a picture of a favorite cuff.  One each day. There will be a new stream for tomorrow.

To start things off, here is a nice Stotz with an interesting key.

My cuff of the day is the first production run BOA high security cuff. This is #7 of 26 that were made. This model was made before BOA started to make conversion kits for Peerless and S&W cuffs. This one uses an integrated Medeco lock.

Here is a picture of my J G 1952 Darby handcuffs. They are of 'false backstrap' style, with the broad arrow marks, "K.E. 2770" engraved on the inside of each lock as well as the keys.  They are one of my favorite cuffs, especially the dark chocolate color of the patina.  They are rather small, and I wouldn't be able to wear them.  There is also a "1" on the swivel.  Note that there are no markings on the cap of the lock, as with most Hiatts or RCS darby cuffs. I wonder how these types were assembled? Perhaps brazed together below the cap?

Steel and aluminium , press button double lock hinged cuff

Mark - I have no idea
Richard - Definitely a collectors item
thenarsian - Rare cuff.  Does your Sheffiel have center posts in the locks?
Ryan - The KE 2770 mark seems to be the army model number.  Nice cuffs
Ian - Nice cuff. Do you know who made it?

Thanks to all.
Everyone else. Find a picture to post tomorrow.

A truly beautiful piece! Thanks for sharing, Glenn! Some nice cuffs brought out to Cuff of the Day post, today! Hope to see more folks partake in the coming days! Both Mark and Ian's cuffs have me stumped. Any ideas on countries of origin on either of those? Very cool pieces!

My March 31 contribution is:

Mark - Nice cuff. Might be a tad difficult for the arresting officer to put it on an non-cooperating prisoner.

Hi,

This is a great idea - especially during this boring period of isolation!

Then I start out with an oddball. I don't know what they are but I acquired them here in Sweden some years ago.
I don't have a clue of origin but these are very well made. The bows are milled, just like the Horst Moabit. They might be a German prototype.
