It certainly was. The only thing to be careful with is using a fine razor saw to remove the windows and the "Doors" - a bit tedious but OK as long as you did not saw into the lugs which held the screws to the body. Other than that it was a matter of cutting planks to fill in Toby's face, and fitting a false floor and bulkhead. All of this can be done from one sheet of styrene card. One thing to note is that I made the floor one plank higher than the original Toby, and painted the chassis black below that line. It make s the model's dimensions appear more accurate.
