Caveney Bottleneck Handcuffs

Here is a working example of the bottleneck design by the Caveney Invention Company. The surface condition is poor but the original key is included. 

These were listed for $290 or best offer and an offer was accepted. 

See earlier posts on Bottleneck Handcuffs for the history of Marlin Daley Bottleneck vs Caveney Invention Company models: Bottlenecks

And past sales of this design: More Bottlenecks

Note the three twist links vs the barrel swivel on the Marlin Daley examples.
