Wanted: S&W Model 94 Handcuffs

[undersigned]

These were circa 1970s. They were high security models with tubular locks and keys. If anyone has originals with keys for my collection, I will buy them outright. Still lookin...

[retdetsgt]

How can you tell the model? I have a pair of S&W handcuffs that I bought in 1972 with the keys, but I can't find a model number. The keys are tublar, but are the 94 different from other keys?
