LNER A1 ponytruck wheels.

[ColinB]

I have been updating a A1 chassis that I bought second hand. The wheels on the chassis were maroon, whereas I wanted apple green ones as I am fitting it to an LNER A1. I had no issue getting the main wheels and the front bogie, in green, then it came to the pony truck. My chassis has the fixed pony truck frame with the unflanged wheels. I could only get the unflanged pony truck wheels in black or red. I thought probably Hornby doesn't do this as a spare. I then looked at my other A1s with the same arrangement and they all had black wheels, although all the other wheels were green. It doesn't matter that much as you can't see most of it anyway. My question is was the pony truck wheels on the original locos always black and Hornby have modelled it so, or are there pony truck wheels on different versions of Hornby A1s that are green.
