Normandy/Belgium Maps

Good evening all.

I’m looking for WW2 period maps of the Channel Islands/Lannion/St. Malo region and Calais/Belgium area that show the rail networks, towns and major roads as would have been used by the pilots of 263 and 137 Squadrons for planning their operations.

(Wishful thinking I suppose but did they have maps that also showed the positions of flak hot spots/positions and enemy airfields?)

I have several missions that I would like to try and map out the approximate routes taken by the pilots. I’ve been using Google maps successfully but would like to make use of maps from the period as many places have had changes to their names, not to mention changes in road and rail networks.

Any scans or titles for the relevant maps would be much appreciated.

Also does anyone know of a suitable reference that describes the types, positioning and number of flak guns used by the Germans on their trains in occupied France and Belgium to protect them from the attacks of RAF Fighters and Fighter Bombers.

As always any assistance that you can provide will be much appreciated.

Paul
