Yes,
There is a photo on
"Slim Rails" N-C-O photos from the "Tom Armstrong collection" of the two cars Go down to
fig.20. The cars were built by A. Meister & Sons. This firm built a number of motor cars, also motor stage bodies, even a streetcar or two. At least one of the N-C-O cars lasted until the end of the narrow gauge and may have been taken to Sparks before scraping.
The Meister & Sons operated under a number of names in the Sacramento area. See this page at Coachworks for more information:
