Hi;

Some later Fw 190s had a squarish wing bulge on the upper surface over the outer cannon position. Some sources cite this a being for the 30mm cannon sometimes installed in the outer wing positions, but it does appear on 190s with 20mm cannon installed in the wings, and even on the occasional F-8 (see attached picture of NASM F-8). What did these bulges actually accomplish, when did they first appear, and how universal were they in the various models?

Thanks!

Paul
