Another "K" stamped Chain Twister Come-Along/Nipper...

I purchased another chain twister come-along for the collection.
It has no maker's brand name on them, but both handles are stamped with the letter "K".
Just like a previous set I purchased recently, I believe these too were German made. Actually, the faint letter K on the main receiving handle on this set, is placed in the same location as the faint letter K on the main handle of my previous German made set.
The two sets look the same, only difference being that the previous set has "GERMANY" stamped in the center of one side of the smaller handle, where as this set has that letter "K" centered on one side of the smaller handle.
Maybe the one stamped GERMANY was meant for export, where as maybe the one with just the two letter K's were meant for their own countries domestic use?
In any case, not much deviance between them, but enough for my interest in keeping them both as representations within my collection

Oh, I had forgotten what the letter K likely stands for... Well, I did a quick online search again, and the K likely stands for the German firm "N.B. Kayser".

Hmm, I was comparing my two sets with the main receiving handles matching in where the K is stamped onto them.
What I noticed side by side, is that one has an overall longer chain, maybe about an inch and a half difference.
Also, while there is no doubt that the two have the same receiving handle dimensions and such, the two smaller handles are not exactly the same dimensions. I would say they are both from the same maker, but likely from two different time frames where maybe there was a slight change in the smaller handle dimensions.
I must admit that before my recent involvement in adding some restraints to my already eclectic collection of gadgets, I would have had no clue on what one of these things were/are.
I am 53 years old, (will be 54 next month), and I simply don't remember coming across something like these "chain twister come-alongs/nippers.
I truly believe that, while most people would recognize most leg irons and handcuffs for being what they were/are, I don't believe the average person would have a clue upon laying their eyes on any pair of come-along nippers.
And especially with the chain twister come-alongs/nippers, I'd guess that folks stumbling upon them in a trunk or drawer after a family member had passed away, they'd more likely than not, simply discard them.
Anyhow, they are obviously not an item in the "amazing mechanical gadget" catagory. They're just basic and simply made tools, and will therefore be less desirable to collectors of restraints. That said, I do find them to be rather interesting for their scarcity and uniqueness within the restraint world ☺

This kind of chain nippers are widely used by modern Czech police

That's pretty cool!
I wonder if they're domestically made for them, or if they import them?
I know that chain come-alongs have been dropped from use by most of the world, but also know that the Clejuso firm in Germany still makes & offers them. I was under the belief that maybe Clejuso was the last holdout of restraint manufacturers making chain come-alongs, but maybe a Czech producer is on that list too. It would be kind'a neat to add one of those Czech versions, if indeed they are Czech made and all ☺
As for the old vintage or antique ones, they sure don't pop up as much as other types of restraints on the online auctions, that's for sure.

I put my four vintage chain twister come-alongs together for a side by side comparison, and am sharing a picture here of them.

The top two are marked with the letter "K", which I believe, from my minuscule online research, are of German make by the "Kayser" company.

The third one has no markings, but was purchased by me with the seller's description of it being a German made/German prison used item. It's the heftiest/thickest linked of the lot, and is the only one of them that was made without a finish, (bare steel, no nickel plating).

The fourth one may be the only American made of the four. It's also likely the oldest. While the others may be old'ish/vintage (maybe 60 to 75 years old, this possibly US made chain twister come-along may actually be antique, (with antiques usually being something 100 or more years old). It's also the only one not based on the Tower design, which the smaller T handle to fit into either side of the larger T handle. This one is based on the Bean design, which allowed the smaller T handle to only mate to one side of the larger T handle. Although it has no markings, it may actually be a Bean produced come-along, (but without any markings, I don't know if I can ever claim that with any certainty).

I acquired these all within the past month/month and a half.
Although they are obviously similar to each other, they definitely have their own indifference ☺

Oops... I meant to say, they all have their own differences

A few different angles of the above come-alongs...

The one at the bottom of the photo, that I believe may be American made, (possibly by the Bean company), has links that seem more hand made than machine made. Each link simply looks less exact in nature than the links on the other come-alongs. It's one of the reasons I believe it may in fact be an antique.
