WWII Issue First Pattern, this pattern is associated with the Battle of Britain in "salt and pepper" fabric, with horizontal crotch zip. This suit is unusual in that it has been manufacturer modified - a ring pull emergency release system has been added. Manufacturer's label Striegel and Wagner with modification label to Karl Heisler, Berlin. The suit is stamped Fl-Gr. G6PP, which we think is the issue unit number. All the zips are original - it is superb condition. This early modified suit would be hard to better.
