These Chinese “H&R Super” style double locking handcuffs manufactured for the Chinese government. These handcuffs are made in large and small sizes. These large ones open 6 1/2″ to 8 1/2″. Includes 2 keys and a nylon case with velcro closure.
Patented in 1934 by Harrington and Richardson, H&R Super handcuffs were given by the USA to the Chinese government to assist in its civil war with communist forces. When the communists won and they ran out of handcuffs, it is believed that they simply made copies, improving the lock design in the process. These handcuffs are still used by most Chinese law enforcement agencies today.
