Here is an old target map used by RAF aircrew in the war.34 x 48cm.
April 1942 dated. R.A.F. Target Map No.6 (d) (vi) 95, Railway Marshalling Yard, Stettin, Germany. Scale 1 :63.360. Intelligence map of the marshalling yards at Settin. Marked with concentric rings around the centre of the target, each ring being 1 mile apart. Marked in chinagraph pencil to top left corner ‘Dummies’ and with 4 red circles.

Lovely old piece that I’m going to frame and pop on my wall.
