My mainstay figures were Airfix, unless it was Cowboys and Indians where Timpo and Britains ruled supreme.
I did have some Marx though, 6″ Vikings from a small corner shop. I also recall some of the smaller Marxmen WW2 British in the toy box at my infants school, l always liked the grenade thrower, less so the marching figure in side cap.
I also picked up some US cavalry, again the smaller, prepainted Marxmen, at a church jumble sale, paying 2p for around a dozen figures.
