smith & wesson model 90

Well i have 2 pair of smith & wesson model 90's.They are identical except one is bigger than the other the cuffs are the same size,but one chain is smaller than the other.The chain as never been changed or tampered with.Need to know what the differance is between the 90 model and the 91 model is.Do i have both models ???

For starters...read my response to the "IDENTATIONS IN S&W 90S" thread, posted on Nov.13,04.

Basically, the model #91s were PLATED nickel.

My error in the above info. Now that I have my notes in front of me...

The S&W #91 was a POLISHED nickel handcuff (although there did exist a previous model #90-"High Polished" model)

...it was the S&W #925 - that was the PLATED nickel model.
