These are probably from the late 1800's or early 1900's. Most likely because of their original height of 10', they came from an old mansion.
I cut these off at the door handles some 30+ years ago and put them in a wall to use as windows. There was a large plate glass window that acted as a weather barrier placed on the exterior side. They are now 7' high X 50" - 52" wide and 3" - 4" thick. They are MASSIVE & HEAVY!
What you see in the pictures is how they appeared mounted in the wall. I had them removed last year to install a large stone mantel gas fireplace. I actually wish I had just kept the windows intact as we have hardly used the fireplace and the windows really brought more visual enjoyment year round.
They would look nice in a residential setting but would also look great in a salon, spa, boutique or restaurant. You could easily spend $2000 on another amenity for your home or business...but, would not get the compliments nor pure enjoyment these will bring!!!
Please contact me at either 607-343-9019 or 607-748-0654. NOT CHEAP! If you have $2000 to invest in your structure and are serious about seeing these...call. Located near Binghamton, NY.
