Hi, the matador is the 5.5 gun tractor, the Scammell was the gun tractor for the 7.2 on the old 8" carriage and a variety of pre war guns, The 5.5 was the only gun I could find as the majority of 7.2s were given to the Indian army after the war. I do have ammunition boxes, drill round bag charges, dummy shell and a couple of fuses along with most of the equipment strapped to the gun if that is any help.
