I have two semi-circle window blinds (arched shutters) for window arches. They are white and are 40 inches wide by 20inches tall. The little blind pieces open or close to adjust light. They look really nice. They will fit windows larger than that by several inches because they have a moulding around them. They were pretty expensive but my wife custom ordered the wrong size, ouch. I will trade them for anything. I could use a stripped AR lower and lower parts or anything for an AR or UZI. Really just about anything.
Thanks for looking
