This set of handcuffs sold for $457.50 (Plus $22 Shipping from Sweden).
Up for auction is a very rare and beautiful set of the Finnish Konepaja Voima handcuffs. They were patented in July 27, 1928 by Kosti Albinius Hangelin in Helsinki, patent # 12928. The shape is quite similar to Harrington & Richardson Super Handcuffs 123 with a U.S. patent from 1934. You can say these handcuffs are the forerunner and the original pattern. Their appearance is also somewhat chunkier compared to the H&R. One bow is stamped “Konepaja Voima Helsinki” and the other “PAT HAK No 1731”. The stamping “PAT HAK” mean Patentti Hakemus Numero” = Patent application number.
These handcuffs are in excellent condition and have never been rusty. Very smooth action. They double lock by turning the key anti-clockwise, just like the H&R. This set doesn’t come with a key but an H&R key works excellent and is very easy to get for a few dollars.
The shipping cost is $22 worldwide, insurance is extra. - eBay
