Leaded Glass Windows

This is a picture of the leaded glass windows (just 2 of them) that will be on either side of the fireplace. I found them on eBay. They came out of a house (circa 1919) which was destroyed in Detriot, MI. My dad is going to take them and refurbish them for us, building up the frame so that they will slide in as inserts to the Marvin windows on either side of the fireplace. (Fingers double crossed all our measurements are correct.)
