This is what I am learning to breech seat with. Top one, new to me. Built by Schwartz (Wayne I believe) built in early 80's . I topped it with an old balvar. Came with a ton of correspondence between builder and owner (Gibbs.) Last owner sold it to me as a 30-30 but the paperwork appears to reference another caliber. Bore is .310. 2 breach seaters. Cool custom stock with removable comb for loading with the straight seater. I believe that was done by a peter shuttleworth, it is in papers.
Second is a Barry Darr build, action serial number is 3 digit. Was built on 1971. It was a personal gun of his, am the 4th owner behind a Bob A. (All I know, lives in iowa) then Virgil Davis. It is 32-40 with cam type seater. Topped with a unertl programmer 20x
Hard to even see the seam in the woodwork
Paperwork
Even referencing the ASSRA, last paragraph
