This past fall, there were several Rosses sold at Gunco in Nepean. Mk. IIIs with uncut stocks, were between $200 and $650, depending on condition. The most expensive was DA marked (ex HMS Canada/Almirante Latorre) with matching numbered bayonet, about NRA Good condition. In superior condition, prices could be higher. Mk. II prices seem similar. Cut down service rifles sell for $75 up, depending on what is there. I know of particularly fine unaltered rifles selling for over $1000. Unaltered service pattern Rosses in premium condition are uncommon. You will see dozens of unaltered Lee Enfield service rifles for sale for every unaltered Ross. Most Rosses saw a lot of service, and their condition shows it. Rosses were long, Mk. IIIs in particular being rather clumsy, so many if not most were cut down once they were in civilian hands.
