A couple of years ago I picked up a non-powered Atlas GGM&O F3 here on the Forum. It is a thing of beauty. From time to time I would post in the Wanted section looking for it's twin - either powered or dummy, to no avail. I enjoyed running it on the layout with a short passenger/mail train which consisted mostly of setups for photos. I rarely 'ran' it as the only other GM&O motive power was a pair of RK RS3s but the colors didn't match very well.
Last year I obtained several diesels from another member who was narrowing his roster and among them was an Atlas Santa Fe Warbonnet F3A single. I contemplated having it painted to match my original unit but figured I'd keep looking for awhile. I wrote to Atlas and spoke with Bill in service. He told me to be patient as he may come across one sometime.
6 months later I spoke with him again a York and he encouraged me to keep trying so I did. Finally a couple of months ago I wrote again and he said give him a few days, and sure enough, he found a cab for me.
I pulled the handsome Warbonnet cab (visible in the rear of photo) and sprayed the chassis black. Swapping out the scale pilot and coupler held me up for a couple of weeks as it involved cutting some of the metal on the powered unit. Just this evening I did it and mounted the new GM&O cab - she certainly looks great now as an AA.
I'm offering the Santa Fe cab for sale if anyone is interested. These Atlas models are first rate!
