The windows arrived and I had a fun 2 hours getting them, paint and a window price for the window seat. Then didn't get the screens so had to go back - add another hour. Other than the hardware not being brass, everything looks OK and ready to go.
I'm still debating what to do with the window seat windows. Look like getting two casement style with the lattice grill work (custom) to match what was originally there will end up setting me back at least $1500. Getting a pair with the standard divided light grills is around $900. I've had no luck finding originals in the size I need. I bought a pair a few months back with beveled glass that matched the sidelights for the front door I'll be installing, but they're a few inches narrower and I now don't thing will look right when installed. There's also the matter of being able to open them and efficiency which getting an original probably won't allow. But I do need to come up with something this year.
