Do you have an idea of how old it is? Anschutz made two basic "series" of bolt-action rifles in 22 Hornet, the 1400 series (which includes the 1422, 1430, 1432, etc.) made up until 1988, and the 1700 series (1700, 1730, 1732, etc.) after 1988. The differences in each of these specific models comes down to things like single trigger vs. double trigger, adjustable sights, vs. drilled and tapped for mounts, heavy barrel vs. standard barrel, and so on.
