My 12-gauge Black Diamond --

The Black Diamond was the first Tobin I got. Found it at the Rockingham County Fairgrounds gun show in the Shenandoah Valley in the spring of 1988. That gun and the Tobin ads I was finding while researching things Fox at the Library of Congress and feeding the info to McIntosh for "The Finest Book in the World" as Headrick nicknamed it led me down the Tobin rabbit hole!!
