1937. Marlin Firearms Co. Tom Mix endorsed a Marlin rifle called the "Tom Mix Special .22 Caliber Rifle." The actual rifle is inscribed w/his name. Mix appeared in Marlin ads promoting the rifle. The same ads offered a "Simulated Gold Military Type Ring" and a booklet by the National Rifle Assn. titled "How To Set Up A Rifle Range" for 10¢. Later, the rings were also offered as a "Gold Bullseye Ring" available to boys in lots of 10 or more at 6¢ each w/suggestion that the rings be resold for 10¢ each and used as an insignia for members of a Marlin club. Still later, in the 1950s, Marlin gave away the ring from their booths at NRA meetings and exhibits. In spite of numerous offerings, quite scarce. This one has tiny bend on one lower prong and missing luster on lower prongs but luster on top half is glossy and N. Mint. Most versions have black paint accent on target circles but this one appears to not have color as made. Top half displays Mint.
