Greetings, David,
This is about all I could find during my research on the Gilon, which I affectionatly call "Thumper". This is a link to littlegun site. Once there,
click on Belgium "E" on left side of page. Click on "Identified Craftsmen".
Scroll down and click on "Gilon N. Joseph". The big honker shown last is the actual revolver in my possession. Not much information, but a place to start.

If your interested in the work I did to give "Thumper" a second chance at life, take this link.
