One other interesting part of Marlin records revolves around the Ballard line of single shot rifles Marlin built. In probably close to 50,000 Ballard rifles that Marlin produced, only about 16 got recorded between 1875-1891.
So why didn't Marlin record the Ballard rifles, and why did about 16 of them get recorded one day?
The answer is likely because John Marlin never owned the patent rights to Charles Ballard's design, as it was owned by Schoverling, Daley, and Gales. John Marlin was given 5% of Ballard sales, plus paid for each rifle he produced. So not having a large interest in the Ballard, he saw no interest in recording them.
The 16 that got recorded one day. Likely whoever was their full time recorder was unable to get to work that day, and his temp replacement didn't know not to record the Ballard rifles. So he added those finished that day to the records, and of course nobody was going to scribble them out of the ledger the next day.
Were it not for the success of the Ballard rifles for John Marlin, it's questionable if Marlin would have ever gotten into the lever action repeating rifles we love so much! John Marlin had never built a rifle in his career at Colt, or at Marlin before 1875 when SD&G approached him to take over the Ballard manufacture. But he was so successful that it supplied enough profit and experience to allow Marlin to venture into the lever action rifle business. Sadly that success also allowed John Marlin to tell SD&G he had no interest in continuing the Ballard rifles in 1890, and the Ballard rifle ceased to exist.
