A.A.Brown made some of the Alex Martin ribless guns.A ribless 12.G Boxlock ejector by Alex Martin [but believed in this instance made by A.A. Brown]sold recently for $5,000 Cdn;Or Approx $4500 U.S..This was truly a best gun.It appeared to be in unfired condition. The finish was typical of the standard of excellence seen in guns made by A.A.Brown.
The Mitchell library, University of Glasgow, has information on the Alex Martin ribless gun posted on their web site.
