This has come up before and from what we have been able to tell the actual name of the gun is The Interchangeable That is always on one side and on the other is Rodgers Machine Gun,Keystone, and Pritzlaff Quality to name the one's I've come across. I've also come across two possible manufacturers The interchangable Model of 1901 was made by Simonis, Janssen & Dumoulin who were Belgium gun makers from 1884 to 1905.
And Neumann Freres who was located in Liege Belgium circa 1863 - 1924
There is aprobably an ELG somewhere on it isn't there?
