And now that I look again, I see that your staircase newel is the same as mine. I guess here in Northeastern Vermont they were still using styles from 10-20 years prior.
This comment made me think of something. Newel posts in this style were made for probably 45 years. I have catalogs from the 1890s through about 1940 that feature similar newels. For as long as they were made and as many companies that made them, I rarely see this particular newel post in any of the architectural salvage businesses I frequent. You would think they would be all over the place.
Nearly every house I went to look at, barring one or two that were probably very budget when they were built, had newel posts and stairs in this style - that's partly because I specifically wanted to see pre-1940s houses, but it also speaks to their popularity! Interesting that they don't turn up in salvage yards. I wonder if it's because (I'm not biased at all) they're so beautiful and timeless that even when people are updating their homes, they keep them?
You have the same weird bathroom layout that I do. I've looked at most old floorplans and usually the tub is right under the window.
The apartment I'm in now, in which the bathroom probably dates to the late 1920s, has the tub right in the window, and I definitely prefer that arrangement. But if the wall boxing in this tub were gone and the space had some more natural light, I'd like that too!
Re: the kitchen layout -
The back half or third, including the fridge alcove and the dropped ceiling, is newer than the house - it was originally a porch, and got enclosed at some point, probably in the early '80s with the rest of the big changes. I would bet they put in the outlets as a just-in-case move, as there's a door just to the right that disincentivizes you to put a table or appliance there permanently. (I have a small 1860s(?) table that I'll probably put in the middle of the floor instead, unless I find a better place for it.)
