This is a model 1905 considered 4 th change manufactured in 1919. It's in 90% condition and numbers matching. This was a U.S. British Lend Lease gun, which means the US sent it over during the war for England to use. It has all the British and American military proof marks. This gun has its original bright blue finish not a military parkerized one, somehow it escaped re- finishing, thank goodness. It has a 2 inch barrel, wood grips and is in amazing condition for a 100+ year old gun. no trades. Thank you.
