I have been stripping the paint from this chair and under the silver – the black – the light blue – the white and the grey was the original chromate green and a makers label.

It was made by General Fireproofing of Youngstown Ohio.

WIX has shown that these chair were used post war on C-47 and B377 Stratocruisers as shown in this image.

The chair is an evolution of the Good Form chair and was probably widely used due to comfort.
