Thank you, Rich and Al, for the responses.

I wanted to beat up the car, bowed sides and dented panels. But if the G25b's were rebuilt around 1951, the time of my interest, then the cars would have looked too fresh. They would have had new paint, and probably not as worn out as I would like mine to be.

I could back date it to a G25a, all the parts seem to be with the kit.
