David as a Belgium member I want to clear something. The locks that you pictured as a Bury lock is a picture of the lock from my friend Daryl's Christophe, but that is less important.
He can confirm that but he is outside the U.S. till may 20
In my opinion I think that the Ugartechea was originaly of Belgium manifacture and exported to Spain, unfortunately I cant proove it. Bury produced self openers " or easy openers".
Many U.S. members not know that we had also, sidelocks makers "platineurs" to say it with a French word and one of them was Nicolas Jacquet who lived in Cheratte a city near Liége. Again unfortunately in our country there are no records kept like in the U.K. and that is pitty. But maybe these locks are made by him.
