Found this on the attic floor, which is the outside of the upper crate. I have probably mis-named this as Apple crates, since the box sides are solid, not slatted. I think the wood boxes for apples needed slats for the air could flow through the box. By enlarging this on my 20" computer monitor, it seems to read: Ed Hindler Co; Dayton Wash.
Dayton is a very small town in Eastern Washington, about 350 miles from where I live now.
I Googled the town, and the company, and found this: James J. Edwards, the highly efficient president of the Edwards-Hindle Company, conducting one of the leading department stores in southeastern Washington, is recognized as a foremost factor in the commercial development of Dayton.
Mr Edwards worked in the store, then bought out the owner, who wanted to retire, and Mr. Edwards then revamped and renamed it the Edwards-Hindle Company - in October 1906.
So my little house is no older than 1906 - and that year keeps popping out at me from all sides. I also have a photograph of my great-great-aunt in 1906 - and 20 years ago I made a room box depicting that picture.
I highly doubt Mr. Edwards had anything to do with this little dollhouse, except to provide the boxes through his store, as he was a very wealthy man and could have purchased the best dollhouse on the market for his little girl.
