Varying sizes. I'm not going to measure every single one. Original wood frame windows with a lot of them glass intact. Storm windows of varying sizes with glass or mesh screen. Cherry pick what you like BUT PLEASE don't just throw them all around. Leave em propped as neatly as you found them. Don't break the glass on the premises just to take a frame.
Everything will eventually go to the dump as soon as I get all related items together. Might take a couple of weeks. Bring work gloves for handling as well. A lot are dirty from 20 years of storage. Also some random stuff will be there as well should it fit your fancy as well.
