Posted this gun over on the Marlin forums and received this back on the scope from one of the members over there...
"FYI According to Nick Stroebel's book "Old Gunsights and Rifle Scopes"page 557 Marlin scopes were made by Wollensak of New York in the 1930's but were dropped with the onslought of WW2.However production was resumed in 1958 by The Soverign Instrument Co.of Dallas Tx. and was continued untill 1986."
