I don't know if this question will make sense. Is there such a thing to hand cuffs as a Flayderman's Guide to Antique American Firearms? My uncle left me his gun and hand cuff collection and I would like to know more about the hand cuffs.
Thank you.
Russell:
You indeed have a treasure in your possession.
About the only suggestion I can make with respect to your Peerless collection is to go to the U.S. Patent and Trademark site and download the FULL version of the following patents:
1017955
1157135
1161562
1531451
1872857
In looking at these, don't just look at the diagrams; carefully read the descriptions and claims made. Compare those to what you have. In general, and I'm no expert, here's what you will find:
1st Peerless: Had two variations:
(1) One connecting link, stamped with Mfd. by Smith & Wesson, had serial numbers, 1912 patent date, a patent pending and other stuff. The collectors out there think this one is really super, I guess because it has Smith and Wesson stamped on it.
(2) Two connecting links, no serial numbers, 1912 and 1915 patent dates. There were fewer of these made than the ones stamped with Smith and Wesson
Really easy to identify the 1st Peerless, either variation. Look at the ratchet mechanism between the cheek plates and you'll see it's made of two pieces.
The first model, either variation, could only be double-locked with the key, turning in the keyway. The problem was that to double-lock, the key unlocked the pawl on the way to double-lock.
2nd Model: had no dates for patents, only patent numbers: 1017955, 1157135, 1161562, 1531451. Could be double-locked either with push pin (called a "plunger" in patent 1531451) or the key; however, as noted in the last patent, the ability to double lock with the key was secondary and to be "roughly used".
3rd Model: The Classic Peerless handcuff, later called the Model 300. Made dummy proof and could only be double-locked with the push pin and used a barrel key. With several million made, it seems many handcuff collectors do not realize the variations that exist. If possible to find an original Model 3, here's what you will see:
BOTH double bows stamped on front (keyway side):
The Peerless Handcuff Co.
Springfield, Mass.
serial number on left cuff, between keyway and swivel.
Back of double bows, BOTH stamped:
Patent
1531451 - 1872857
Made In U.S.A.
~Peerless logo on left cuff body (from back).
~No exterior ditch dimples; pawl dogs are drilled and set into cheek plates and are oblong with sloping sides.
~Ratchet has anti-shim groove, described in patent 1872857, but omitted in all later models with only the pawl anti-shim grooves retained.
~Heavier single spring requiring greater torque to operate.
~Total weight: 10.6 oz. (as compared to later 9.5 oz. commonly called the "10 ounce" version).
Oh, well, enough of this.
You have something truly special, particularly with the boxes and paperwork. For that little group tied together, with the odd keys, I suspect that if you examine the box inserts, you'll find the extra little thing at the very end about it using "a quality handcuff key." There's a possible reason for that, but since you're getting into collecting, I'll let you go find that particular patent for yourself.
Russell, happy collecting. You're starting out with an amazing resource, and don't ever let anyone tell you otherwise. They'll holler and pout about their Smith and Wessons, but you have the Patriarch of All Modern Handcuffs: Peerless.
