Regarding windshields, I’ve worked with Aircraft Windshields in Los Alamitos on a custom project a few years ago. They were good to work with and produced a mold and some quality windshields for the Bolkow Junior.
The best contact there is: Jesica@aircraftwindshield.com
If they made Meyers windshields in the past, they may have the mold. Otherwise, someone is going to need to provide an existing windshield and pay the mold cost. I think I paid $800 for it a few years back.
