Title: GWR 517 Class Early Version

I found this image of an early design of a 517 Class tank engine circa 1868, and thought it was worth a G3 version. These engines were built at Wolverhampton, where the CME was George Armstrong.
Armstrong was autonomous from Swindon and designed some sucsessful engines. Many early tank engines had saddle tanks before side tanks became standard design as they held more water.

The photo is the only information I could find, a reasonable assumption that the major dimensions are the same as the later versions of the 517 tanks. Knowing the wheel dia and the distance between the axles I scaled the image to G3 sizes and measured the image to create a working drawing.

The model chassis are 1.5mm steel, with the wheels cut from 8mm ali plate.

Further progress on the 517, I found some figures for the cab. There are no suitable ones for the period of the engine, I will attempt to alter the figure to be more in period. Although I am not convinced, they add much to the visual experience.
