Looking at the picture of the A1 and A2 side-by-side, two questions arise:
Why do the locos look to be much the same length when the A1 should be 1ft 11.375in (almost 8mm in 4mm scale) longer than the A2?
and why does the A1 boiler look a lot shoprter than the A2's when they should be the same length as, according to the RCTS Green Books, both classes were fitted with Diagram 118 boilers?
Please tell me its a trick of the camera.
