I recently purchased a Ross 1905 Sporter (Serial # 6996) in B.C. It dose not appear that there are many close to this serial # on the registry on your site. The stock is a beautiful piece of wood, but I am assuming the inlays were not factory.
It is a 303 and there is a P in the circle (not an R or an E?)
It shoots great and am about to start handloading for it with Barnes TTSX 150 grains. I am now in love with Ross rifles and their history.
Anyone with info on the rifle feel free to message me.http://s2.photobucket.com/user/steve004/media/IMG_0465_zpskkogcqfb.jpeg.html
