FWIW regarding a 28 bore Smith, Hunter Executive and Hunter Family member Waddy Wadsworth reported owning a 28 gauge L.C. Smith to me in 1966. In his Gun Digest article critiquing the then new Marlin reintroduced L.C. Smith Gun many years ago, Gerald Hunter briefly noted Waddy's 28 bore Smith. Its probably in Brophy's, but have yet to own this fine book.
