Rare Remington 1931 “Hi-Speed Kleanbore Silvandry” HP 22 LR Ammo

This is a full box, 50 original rounds, of .22 LR hollow point ammunition manufactured by Remington as part of the “Hi-Speed Kleanbore Silvandry” series of 1931 which only lasted until 1936 and was one of four different Kleanbore loadings of that time period with the Silvandry bullet finish the least popular and was replaced with Kleankote.  In excellent condition this red, green and white one piece box has very nice edges and corners with excellent color and crisp graphics.  The cartridges are in excellent condition.  A rare very high condition example of this short lived and now rare loading.    The box is identified as REM-7.5 LR-3(a) in Roger Huegel's online  .22 Rim Fire Box ID Reference based on the original Dunn classification system.
