Hi,
I don't have so much info about that lock, but I can say it's a french one, Not produced, or at least not sold anymore in the common market.
It does exist in several version, the one you had, but also in europrofile shape too.
And it does exist in 5, and 7 "pins" versions.
The 5 one is very very easy to pick (if you like to pick a lock 6 time to make one turn

)
But a simple tool can allow you to pick it only one time for a whole turn.
I never tried to pick a 7 pins one, but I believe it's not so hard (which is not the case of others french pump locks)
If you have questions about this lock, I may have the answer (or maybe not

), so please ask.
nice blog, thanks
