The leather top 4 arrow quiver with the single bolt ended in 1971. However the newer quivers still used a lower bolt mount that could screw into the stabilizer hole with an adapter or an insert in the riser on the side below the grip. I believe that right from the start in the early 50s the quiver insert was an option, not standard equipped. On the dual self bows the buyer had to request RH or LH quiver mount.
