Been trying to find some decent markings of the British 3.5inch practice rocket mainly on the actual war head hollow charge section, not the rocket motor. There seems to be two practice colours and marks for the war head in a light blue or a duck egg blue. Usually the markings are in white either marked up in HE SUB or M20 practice showing lot number or TX etc, also black inspection marks in black like GD etc. Anyone have any pictures of decent readable markings on their rocket.
