Looking for photos of the Western Maryland G-6 or G-7 class 4-6-0.

Hi, I am wondering whether I could produce either of these from the Bachmann Spectrum Baldwin high-boiler 4-6-0, as both were built by Burnham Williams in 1901 and 1906-7 respectively, and they had 62" and 64" driving wheels respectively. However, Google has not found any photos. Does anyone know where I might look online, or maybe a suitable book, or maybe a magazine issue I could get on ebay? I have looked on Amazon, and WM steam books seem to be out of print or too modern. The last G-7 was scrapped in 1935.

TIA,

Bill.
