Actually you can get old sash, you just have to build the frame for them to go in, which is not as hard. (It might still be pretty hard; I've never done any such thing.)
I notice your kitchen used to be green. I have a theory that every
house of a certain age has either that green (example: My grandma's house) or a sort of oyster pink (my house) in its past. So I'm tickled to see it in your kitchen.
High ceilings are great when it's hot! Transoms were handy for letting that hot air out, although frequently they were set up to tilt open along a horizontal centerline, if you see what I mean, so that you couldn't install a screen to keep the flies out. Of course the porch was the most effective appliance for peeling potatoes, etc. without broiling to death yourself. But cinder blocks? Really? How long did they expect that to last?
I'm often guilty of assuming that everything done in the past was done well, but some POs seem not to have grasped the whole concept of long-term planning.
