Lightest Darbies in the World?

I have been looking at the various darbies in my collection and have been surprised by their different weights. Seems that most of the '101' pattern handcuffs weigh about 275g (9.75oz). Although the last batch that Hiatt produced in the early 1970's weigh 310g (11oz). What I do have is a set of Froggatt light-weight darby handcuffs that only weigh 245g (8.625oz)they are very slim and very beautifully wrought. What is also interesting is they are marked T. FROGGATT which is unusual as most cuffs I have come across made by Froggatt are simply marked FROGGATT. Do any other collectors have lighter models? The weights quoted do not include the key.

Here are the pictures. Chris can you tell us the size of the small Darby in
cm or inches?
thanks

They are a fairly standard size and measure 53mm X 66mm (roughly 2" X 2.625")

I also have a set of Froggatt 101 pattern darbies. They put little over 240g on the scale and are indeed simply marked FROGGATT (see attached picture). The lightest cuffs in my collection are the S&W 926 (not a darby of course) which weighs little over 100g.

Here is a very special light weight German Clejuso Darby (alas not mine!). The tubes are made of aluminum, the rest is made of steel. Total weight is about 240 grams (the all steel version of this model weights about 340 grams).
