I've never seen an engraved version of the A.C. McFarland designed trigger-plate action hammer gun before. The early guns made in Syracuse and then in Batavia had an underbolt and a dollshead rib extension. Later they adopted the wedge-bolted rib extension as on the hammerless bakers. The nice sidelock Model 1897 was essentially offered in two grades -- one with twist barrels and one woth Damascus barrels -- kind of like the hammerless A- and B-Grades. See the DGJ, Vol Nine, Iss 3.
