Sometimes things just "click". While waiting on various items to arrive, I decided to search for the HO houses that will go above the Steubenville station. The Walthers website is a great source; they seem to have the largest number of HO structures on the planet.

I identified a friend's grandmother's house and have acquired that kit. I also have one of the houses to its right (Tillman Farm House). I was intrigued by the 3 identical houses at the right of the Google Earth photo.
https://www.icloud.com/sharedalbum/#B0B5qXGF1G98NiBThey looked vaguely familiar to me. They are Albion Catalog Houses. Yes, you buy the real ones as kits from (get this) Sears! They come unassembled on a truck. Unload the truck and assemble!
Here's the kicker. The reason the house looks familiar is that my maternal grandparents lived in one! My father told me that his father-in-law built his own house in the 1920's. I never explored the subject, but I remember the floorplan and outside appearance of the house. It seems to have been an Albion home with some modifications (expansions). And being a carpenter, cabinet maker, and ship builder (remember the model ships he created?) by trade, this would not have been beyond his skills. This makes a lot of sense.
