The three red-bullet dummies are Australian, first pattern, Mark III’s. The wood distance piece, visible inside the case, was an Australian idea, the British didn’t adopt this improvement until during WW1 with a pointed wood bullet. The same dummy (drill) can be found with CAC headstamps. This dummy was introduced C.1905 by Australia and the second pattern, with an inert primer, C.1907.
The Mark I charger clip was introduced on the 16th January 1903 and the Mark II on the 24th April 1906. So, the charger and dummies are each of the same period. Remember that dummies were re-used many times so they would be loaded in and out of chargers many times, finding an original set is rare, unless in a packet.
The cartridges are not correctly loaded in the clip. The rounds should have the rims staggered, up, down, up along the clip, with the outermost and the centre round being against the base of the clip.
What a pity you don’t have all 34 clips anymore!
