The 1892 patent

This is the revolver that L. Nagant started with at the Russian trials. Close examination of the patent sheets is very illuminating as to the changes that were made for the Russians!

Details of the trigger mechanism. This is very interesting as it shows a double action revolver (which the Russians didn't want!). The hammer block and breech block are quite different than the final version.

The 1895 patent

The 1895 patent shows the basic version of the Imperial Russian contract. It is a single action revolver mechanism converted from the original double action version. These two sheets show the basic details of the new revolver.

More small parts. The hammer block is shown in 2 different versions in figs. 2 and 3. Fig 2 has a hook like the final version put into production, while 3 has a recess that would catch the hammer.
