GP20D HO Scale

This shell is designed to fit a Proto 2000 GP20 frame (must remove weights). The shell is also designed to accept Canon radiator fans https://shop.cannonandco.net/product.sc?productId=76&categoryId=12 1704 and https://shop.cannonandco.net/product.sc?productId=87&categoryId=14 1853 for the dynamic brake. The shell includes holes for grab-irons and handrail stanchions such as those made by Smokey Valley. This is a new product derived from the MK1500D; while similar to the MK1500D, this model costs more because it uses more material, due to the dynamic brake, and it required extra work to design.
