NLS - Ordnance Survey National Grid maps, 1940s-1960s

I noticed these again in "Recent Additions", they tend to be around towns and not complete but shows up the original layoiut of Raigmore well with the two bunkers and another square building which could be the third part though I thought it was nearer the new A9.

I looked at the fuel tanks near Dumbarton also though little showing on the hill North of the A82.

It can be frustrating, half of Inverkip AAOR shows but the other half has not been scanned.

Not relevant to airfields but I went to a talk at the weekend conference about a project to scan the Lovat Estate maps and put online at the NLS. The estate paid for the hire of a A0 scanner and a society provided manpower to do the scanning then the NLS stitched the large files together. It follows a similar larger project in Dumfries. Some beautiful maps going back to the 1758.

Maps in general are frustrating. With many wartime locations you get a before map but the after map can be white space if it's from the forties or early fifties and then when when restrictions are relaxed the place has been cleared. I see a lot of comments online by people who deny something existed merely because it doesn't appear on any maps. You do get some oddities where something is marked on the 25k series but nowhere else.

There is a new issue of NLS's CAIRT out

NLS have added "Ordnance Survey / German Army, Karte von Schottland 1:50,000, 1941 - 70 sheets"

Obviously OS maps overprinted. All that is shown on the local one is the main railway line from the South but not the Mallaig branch and the Fort Augustus line though only as far as Invergloy!

Ordnance Survey / War Office One-Inch to the Mile Maps of Scotland, 1930s-1940s

The NLS have added more maps to the range of WWII War Office mas. These include the 1938 Special Emergency Edition (ARP Edition) which was a rush job showing recently built areas. I noticed the ROF that was up the road from my old home is shown so it helps dating some places like that.

I've never understood why military overprints of standard OS maps fetch more money on eBay as they offer nothing new, except purple lines. Now if they marked military installations that would be another matter.
