Manufactured in 1878 as a Second Model, with dust cover guide retained with two screws and checkered "thumb print" dust cover. The included factory letter confirms the special order half octagon barrel, half magazine, and set trigger, as well as receipt at the warehouse on 20 August 1878 and shipment the following day in order number 12718. The top barrel flat is marked with the two-line address/King's patent marking, and it correctly lacks a caliber marking. The upper tang has the model marking, and the serial number is on the lower tang. The left side of the lower tang has the assembly number "1343", which is repeated in the stock mortise and inside the buttplate. It is fitted with a German silver blade front sight and elevation adjustable semi-buckhorn rear sight. It is mounted with a faintly figured smooth forearm and straight grip stock with a trapdoor crescent buttplate (cleaning rod not included) and six "kill" notches carved immediately behind the lower tang.
