Okay, more research brings it up: Marxville O/S gauge #3792 Deluxe Western Ranch House Set. I had the colors backward. Included a stump with an anvil, a water barrel, a tree, a cactus, a fence, and the items above. It also had 10 assorted cowboys (1950s style TV guys).
I still can't find it, but I found some of the accessories. I'll keep looking.
