British M20 Bazooka practice rocket 3.5 inch markings

[BMG50]

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.

Anyone know what this practice colour is under the BS381c colour code.

Not sure if any of these are British. The middle one is most likely Belgian or Norwegian.

Thanks Slick, quite a few variants of practice colours and markings. Looking at the head I have has a green under the paint where it once was a HE round but has been converted HE sub, it still has the cone in it.
Not sure what practice blue was before NATO blue colours took over as the practice rocket motor and fuze in mint condition I have is dated 1/ 1954, not sure if the colour I have is Turquoise blue BS381c 102, anyone know???
