Any one out there got a Unertl scope manual from the late sixties or early seventies for sale.. How about any info regarding the serial number ranges of the scopes made Ca. 1967 to 1970 s I am trying to buy a Unertl scope from this period to go with my Remington Varmint Special (1967 )

If you did a google search you have probably already seen this site... He has some pages that explain the differences between the various models.
