This is a very unique and easy way, to produce replica Boeing 737 Side Windows. This guide contains 61 pages of highly detailed drawings, a step by step guide, tools used and current costings.  These windows are good looking and will fit perfectly with version 3 sidewalls and front section. Please check out my Youtube video of the window build at: https://www.youtube.com/watch?v=xS8Q2P0V0ZE
