Bagnall Sipat Body in 1/32 Scale

My Bagnall Sipat body scale to 1/32 scale. No provision is made for chassis in 1/32 scale, though you're looking for something very similar in size to a 4mm scale L&Y pug chassis (eg. Hornby or High Level) for wheel diameter and wheelbase (the prototype had wheelbase of 2'6" and wheel diameters came in several sizes ranging from 13" to 18"). You would need to make your own cutouts for the motor. The cylinders are provided on sprues so that you can attach them to your chassis, though the square sprue will align them with the square holes in the smokebox saddle to ensure they're kept at the correct angle/alignment.
