Provenance is :

i purchased it from a chap who came in to my shop in Brighton along with a couple of other bits i was just told it was a stuka wing panel !!

the wernummers I have seen on removable panels from Ju88 and Me110 were all hand painted.

This one is also hand painted – 10 mm high.

Looking at the 6 – it was not a marker pen as the over top on the 6 would be ending or over the main leg if it was a pen. If it was brushed it would start from both sides and meet at the bottom.

For sale recently on eBay – just as a stuka part – no other provenance – I just confirmed its identity as a Ju87 hatch from the technical plans.

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.

Thank you Sir – so two B17’s with these added post war and used in positions. Easier to see why it was misidentified.

Next question then is why there were any spare ?

Thanks Ian – thats the one!!

The plans show that end is 40 cm wide – so matches in that respect too.

So it is the starboard side Landing flap end cap.
