Here's the proof: first Lloyd's and Cleeves' batteries. The Perry nine pounder RA crews, in full uniform and in shirtsleeves are the figures. The paints are again craft paints for the most part, with the metals (steel and brass) by Vallejo.
Cleeve's battery K.G.L.
Lloyd's Royal Artillery
Next up, the RHA batteries of Mercer and Bull. I do not know which two batteries were with the guards on the west side of the field, but these two represent the nines and the howitzers present.
Bull's was the troop equipped with the howitzers.
Mercer's were armed with nine pounders.
Final shot to see they are not parading around to fluff up the count.
