The 3 Ton wagons were less numerous than the 2 ton variety, yet sported a vast number of construction differences. This is a Brown Marshall built example, and has been created to be as accurate as the 3D Printing process will allow. Only the thickness of the metal sections has been compromised - and even then only by 0.2mm, making this an incredibly detailed and faihful representaton of these wagons. Complete with functional couplings, requires only axleboxes AB01 or AB02 to complete, along with Slater's wheelsets. Some minor drilling of the axlebox is be required to rebate the brass bearing a little deeper, due to the dead scale positioning of the underframe. I used a 5mm drill bit in a pin chuck to do mine, only a few twists are required, the material drills very easily.
