I'm currently doing a few research about keys with a moveable element, and the locks which come with.
Here is a list I made and I hoped some of you could help me finding other ones :

Bricard Supersureté with ballbearing *
Dierre Atra New Power (must be confirmed, I'm not sure it's moveable) *
DOM IX 5*
DOM IX 6*
DOM IX 10*

Dény Fontaine double-bitted with spring loaded end ( already manufactured ??? or only a patent...)*

Do you know other models ?
The ones with the star * are the ones I'm looking to get (buy, trade, or gift

By the way, do you know which one is the first of the world ? which patent ?
I think it might be DOM, but not sure, neither do I have the patent number or the date.
Bye Bye,
