Recommend Frosted Ultra Detail for printing. This is a sprue of five (5) 1:400 scale models of a flatbed semi-trailer (trailer only). This scale matches many common model airport scales and is very close to T-Guage railroad models (1:480). The photos are of my other model which has handrails and a staircase; however, for size and color comparison, the basic trailer is the same. Thank you for visiting my shop, and thanks to paulburkittgray for creating the model.
