John shared this photo detailing a stencil on the windshield: Max Capacity 5 Person. He hoped it would help any folks doing a restoration.
He wrote, “Over on a Warbird forum someone posted this photo of a B-17 crew in the UK late in the war. I have blown up the photo for details….specifically, the tire pressure stencil on the base of the windscreen frame…and the “Max capacity 5 persons” notice..Might be of interest to someone restoring a wartime vehicle. The photo is from the national archives… so no copyright.”
Here is the original photo:
