Armor plate was the bottleneck and why only four were produced. Taylor mentioned a FT-17 without a turret but two sponsonson the side. Steel rods through the drive wheelin the rear engage castings on the underside of the tread plates to positively movethe tread. They are not on the drawing of the side view.
