I just won two windows on e-Bay. i had hoped to retrofit one into "Itty-Bitty"; but after reviewing my build pics, my main electrical feed runs right though the area the window would go, so it won't be as simple as i thought. So, if any body is interested I have a window for sale for what I paid or it.
New Aluminum framed Slider window with screen
outside dimensions: 12 1/2" high x 37 1/2" wide
hole size- 10 3/4" x 36- Dark Gray Tinted Glass

I paid $22, that's all I'm looking to get back plus shipping to it's new location.
