Does anyone have a photo of a Baldwin riding on Batz trucks? I remember reading somewhere that it was a Santa Fe patent and that Baldwin had been licensed to use this truck design. I dont know if Santa Fe,s Baldwins were the only one riding on this type of truck. And I have run accross someone who has never seen it. I know it looks similar to the type B truck but different that it had a lower center of gravity I think?
I think the OLD Kalmbach "Diesel Spotter's Guide" had a photo of the truck. I think it was used on only a very small number of very early Baldwin switchers-- a number in single digits!
Visually, at least, the truck resembles the pilot trucks of (BLW-built) 4-8-4 steam locomotives of the Santa Fe (and also, i.i.r.c., of one of the norther transcons: NP or GN).
For railroad photo archives: "Railroading in the Northeast" (may not have the wording exact) and the "Fallen Flags" site are good (though it would help, in finding a photo on "Fallen Flags," to know what railroad you were looking for).
