Interesting Partial Box Kynoch Adaptor Cartridges For 303 British

This is a partial box, 38 original rounds, of .303 adaptor ammunition manufactured by Kynoch for the Kynoch adaptor enabling one to fire a small pistol cartridge in a .303 British rifle.  The rimmed center fire cartridges are head stamped Kynoch Adaptor.  The two piece box has a mostly intact yellow label showing the Kynoch Lion logo with a partial red, gold and white smokeless powder over-label.  A scarce partial box of Kynoch's solution for less expensive and less powerful training and practice ammunition.
