Keys from "The Wizard of the Army", "The Great DEVILLE" of Manchester England

I bought five keys, shown in one photo, from a guy who was in contact with this magician until the day he died in 1970. No doubt he used them in handcuff escapes. The other group of keys had no interest for me,
Here is the quiz. Which cuffs do you think some of them will open.? Starting at 12 o'clock, 1,2,4,5,7,8,9,10 o'clock .

The ones I bought in the other photo are for Hiatt Figure 8, Boer War and possibly a screw key figure 8 nipper, a darby and a Sheffield darby?

Big ring keys (in my opinion)
12:00 looks like a payphone key but not enough grooves on the side for most American locks.  A lever lock for some kind of banking drawer or other locker where they need better than average security.
Clockwise next Not sure if an original HC key but it would work in a Harvard or Spanish type of cuff.
Next two are Japanese, Spanish or similar HC originals.
Next is possibly a HC aftermarket key by Australin or European make,  Could be American but it could be cut down, so it could have fit anything.
Next on at about 7:00 is not a typical US key but it may fir a cabinet lock or trunk.  Doubt it is a HC key.
The next is a Brahma key most likely British.  The Houdini Mirror Cuff had a similar (but longer) style key.  Considered a hi-security key in the day.
9:00 Could be a key used in French or Czech cuffs.  Does not appear to be original but it is possible.
Bean Cobb/H&R non original but looks good.

Small ring. 
I agree with your assessment on these.

Thanks Mark. Considering he was an English escapologist, I would have expected more English keys such as the thinner 'plug 8' key but maybe there were many more keys once. And some, as you say, may have been for trunks. I think we established some time ago that the Mirror cuff also had a short version, but I don't want to open that can of worms again.
I just thought it would be interesting to give an insight into the escapologist 'tool kit'.

The 9 oclock key on the big ring is for a "high security" Alcyon Spanish type handcuff. Like this one.

I was very pleased when the keys arrived. The Sheffield Darby external thread key was exactly what I thought it was, and works well on my cuff. Now I just need an English screw-key nipper to test the other external thread key on. Getting original rare keys is almost as good as getting he cuffs, but not quite.
