I already have a "3 gun battery."

Ruger 77/22 All Weather (boat paddle) with open sights.
Remington 870 12 ga 28" bbl., matte black finish with African Walnut stock.
Winchester 70 Stainless Fwt 308 Win (open sights to be added).

Throw in my Ruger Security Six 4" Stainless 357 and all bases are covered.

Probably not strictly "old school" but none are dialers and all are pre-1984 designs.
