Made in 1983 and yes, it is listed in the 83 catalog.

Satin nickel finish, pistol grip was also shipped with it. 22/20 ga, cyl choke, 2 3/4 and 3" shells, 6 lbs.

Is not listed as having a buttstock that carries extra ammo yet the 24C is, gun sounds correct to me, I'd grab it if you have the chance, you don't trip over many of those models.
