SHOTGUN: H & R - HARRINGTON & RICHARDSON MODEL SB-1 - TAMER, SERIAL NUMBER HX 260765, OTHER, CASE NOT INCLUDED, BREAK, .410, 19" Notes: The Harrington & Richardson (H&R) Tamer SB-1 is a compact, single-shot shotgun based on H&R's break-open design. The Tamer was produced as a rugged, relatively lightweight field/special-purpose firearm, with models commonly chambered in .410 bore and a 20-gauge version also offered. The .410 Tamer is particularly recognizable for its synthetic thumbhole-style stock, corrosion-resistant matte nickel finish, external hammer, and shell-storage compartment in the buttstock. H&R's literature describes the Tamer as having automatic shell ejection and its Transfer Bar System.
