Caveney and Marlin Daley

Both of these companies used the bottleneck design. 

These are on sale for $350 or best offer. They have 1 key. This is a screw in key much like a Darby key. They have 3 twist links and no swivels. 

Here you can see close up the Caveney makers mark and the Darby like keyway with recessed key post.

This is a very nice Marlin Daley bottleneck. It has the same shackle and lock body design but the key is a two pronged key in this version. 

These were listed for $500 and an unknown offer was accepted. They have 3 bent round links and no swivel.

Here is another amazing pair of Marlin Daley Handcuffs. This lake has a cylinder swivel. 

Here is a close up of the shackle entering the lock case. You can see the Marlin makers mark on the circumference of the tube. 

This beautiful item was listed for $625 and an unknown offer was accepted. 

Here is another set of Caveney handcuffs with the screw in key, no swivels and 3 twist links. These sold in early January 2025 for $202.50 after 20 bids.
