From the initial year's production of Marlin 1895 rifles I observed in 1973, from such rifles I have observed over the last 33 years at gunshows and gunshops, confirmed by Marlin in a conversation in 1974, confirmed by several owners of the initial year of production Marlin 1895. The initial year of production also is distinguished by a ballard-type rifling not microgroove.
