Fredmad - thanks for the photos. I wonder why Mottura changed the design to put individual springs on the sliders?
I also have a anecdote to share. I got the Mottura pump lock from a locksmith in Paris some years ago when I was travelling and didn't have a lot of extra luggage capacity. I asked the guy at the shop for a screwdriver so I could just take the cylinder off the lock. To my surprise, the cylinder did NOT come off - it was joined somehow to the front plate of the lock. This was quite annoying, since I didn't want to have to carry the extra metal. At any rate, the shop guy was happy since I left him the rest of the lock (bolt assembly, etc), which he no doubt used for spare parts.
cheers
