1890s Mortise Cylinder - Help, I need information and a key blank!

[Russwin1892]

My next door neighbor has a home built in 1895 (so far as can be told) and i thought nothing of pulling the original lock cylinder to have a new key made. Unfortunately for me, the key is an obsolete key, being of a U shape. The patent on the cylinder I believe says, "Pat. OCT.27-95" Although the "95, could be an 8/9 and a 5/6) One locksmith suggested that the cylinder may be a Schroeder, another says that he may be an Eagle. I guess it has a double pin mechanism that each leg of the key activates. I am curious to the manufacturer, the actual patent date, and I'd like to find a key blank for it. Any help would be much appreciated.
