screw key padlock

Cool!

That IS cool !!
What is the barrel/tube part made from ?

I would love to see blue prints for this one. I have never heard of one.

Awesome.
Have you got a couple photo's?
Maybe one of it open or from different angles, so people can see how it works.

historicallocks.com has 'blueprints'

Locks fascinate me. Any chance of a thread on this one?
