Unknown Cuff From Russia

I thought I would add this cuff to the list of unknown cuffs that have passed through these pages. This was a recent Ebay find. The gentleman who sold it, was from Russia. I ask him for details on the cuffs, but he didnt know anything about them. So, im asking any of the members here, if they have seen or have anything like this cuff?  His ad did say that it was a Russian made cuff. So, im loosely using that as a beginning point. They may have come from somewhere else, tho.

The lock is really simple. Solid post key and a single pawl. Lots of room to stick anything in the key hole and pop them open. The springs are really light. But both are about the same tension. So, I believe the springs may have been like this or close to this, when the cuff was made. You can barely here the ratcheting upon closing them, but they do stay locked. I tried bumping them on a hard surface to drop the pawl, momentarily, and escape that way, but it did not work for me. The shape of the cuff's body is odd, as you can see. It was pointed out to me by Ian McColl, that the shape of the cuff, fits well in your hand to help with handling the cuffs while they are put on someone. It does fit, very nicely in the hand.

I dont think these are a production cuff. But, i suppose its possible. The swivel is more artistic, than you would see on most production cuffs. The connecting links are also not welded shut. If it is a production cuff, there couldnt have been many made, since I have never seen another? But, i cant see this being used in any type of professional setting? There are no stamps, anywhere on the cuffs. If they were made by someone, just as a single cuff, for whatever reason, they have been nickel plated. They may have been a test done by a cuff maker somewhere? They didnt approve the design and scrapped it, maybe? I am at a loss. I dont have anything to go on and only limited by my imagination, at this point. They are made pretty well, tho. Thoughts?

Initially, these handcuffs were sold in Russia, on the Avito trading platform like Ebay, and the original location of the trader was Crimea. The original price was 1200 Rub (approximately $ 17). I know only one person who has a similar model in significantly worse condition. This person is from Ukraine. So the origin of this model is most likely not in Russia, but in Ukraine. In the countries of the ex-USSR in the late 90s, there were many small companies that produced many handcuffs that were never used by official law enforcement agencies. They are used only by small private security companies. The main problem with handcuffs in the USSR and the  ex-USSR is the almost complete lack of information about the manufacturer although there is an exception. For some models the name is  known, but in some cases it is not the official model name of the manufacturer.

Thank you Rasberius! Is good to find someone who is actually familiar with this particular cuff! I have a few Ukrainian cuffs in my collection. I will add this one to this list. Your comment also helps me by letting me know, that finding the maker or model number of the cuff, probably isnt possible. Just knowing the actual country of origin, helps. It also helps knowing there ia at least one other one out there, that is known of. I appreciate your insight and input on this cuff. Helps solve some of the mystery.
