As Randy alluded to, there were two 99F's. The early one with with schnable forearm, straight stock, NOT drilled from the factory, 1920 to 1940. Then the late F, rounded forearm, kind of like an R, drilled from the factory, made in the 50's-?. I'd like a 250 in either. The 50's F may have been pretty much past the hay day of the 250, and was made in 243 and 308, so it is probably far and away the rarest of the 2. As Randy did say, for a 50's F, yeah good price.
