I am brand new to this forum , spent hours trying to research my model 1899 .303 model # 72.221 and am still confused .... OK .... here's what I have so far... It has a 20 inch barrel and is a saddle carbine with the staple on the left side of the receiver as you are holding the gun, 21b rear sight a knife edge front sight ,carbine butt stock and a Schnabel front. I received a letter from savage historical services that informed me that that I have a 1899-c that was built in 1906 .. the information I've seen tells me it should be an 1899-f any help would be appreciated .
