Hi Don rustyrelx, I owned a #1 in 22rf. It's serial number was in the 9500 range, with a 30in barrel and standard sights. I believe Remington made very few #1 sporting rifles in 22rf. Yours sounds like a very nice gun. There is alot of information on #1's in Roy Marcots book "Remington Rolling Block Rifles, Carbines and Shotguns".
