Thanks Vykkagur & Sharps 45-70....the adjustable rear aperture was found at a gun show and used on this rifle as well as a Motty Special....I will check to see if there is a name on the aperture...It has been years since I have had the barreled action out of the stock....where would I look for "2" on the barrel? I am sure I have slugged the barrel and will have to look for my notes on bore diameter....would date of production most likely fall between 1908 and 1911?

I am getting on in years and have been slowly finding new homes for some of my collection and the Ross will need a new home soon...is this site a good place to list for sale?
