Second Stotz

 This pair came up after the previous pair sold; I see this often, where a high ticket auction sale brings out a slightly less mint version of the item for sale. 

This Stotz has a good nickel plating with some tarnishing and light rust. It sold for $338.50 after 6 bids with the original key.

Above, close up detail of the single O ring and clevises. Note the cuff profile is rectangular similar to Towers Detective. 

Below, one of the bows is broken off. It may still be usable, in that two of the five locking indentations are still intact.
