You could try the HaT British Rocket troop (24 figures) or Italeri/Esci British artillery (16 figures). Both are still available on Ebay at reasonable prices, though of course you get fewer heads. Also the old Airfix British horse artillery (11-13 figures).

Hi Asher, maybe I could solve your problem. But to do that, I would need to know where you live.... because of the possible postage /customs fees.. :money_mouth_face:
