Oil tank mounting hardware kit for the horseshoe style oil tank used from 1936 to 1957 on rigid frame springer and Hydra-Glide big twins.  As the bolts are CP-1038, they would be "correct" from roughly 1949 to 1957, but will certainly work for any '36 to '57 big twin.  

There seems to be some misinformation on CP bolts and "reproductions".  Chandler Products has always been willing to produce these bolts with large minimum quantity orders. There's either early production or current production. They changed head dies as they wore out and had multiple dies.  If you notice there are two styles of CP-1038 stamping on these heads.  Nuts are USA made using the same process Harley used when they operated their own screw and nut equipment with the flat lands on them.  Spacers and washers are produced just like the ones H-D did back in the day.  Parkerizing is same finish as how these came from the factory in the 1950's.  I've also got other hardware kits listed in my store under "pre 1980's hardware" including a CP-1038 gas tank mounting kit which would go great with this.
