Here’s some shots of where I’m up to on the B wagons. The handrail jig (bill bedford) is excellent! The trial footstep is on wagon 3. You will note that not all the wagons have a full complement of the small handrails, and that is as per the prototypes.
I also gave Dolgarrog an initial coat of paint – blue and black on the body, red on the buffer beams and yellow on the handrail.
