And BINGO.
I was wrong about the zandstraat and valkenberg, I presume. (!!!)

Damn this feels good! I got an copy of a map from 1811 - 1832
And there above the text Lage Heide you can hardly see... "steenbakkerij" What means stonebakery!

1811 - 1832


Here on my map from 1944. Here they call it "Pannenbakkerij". "Pannen" (=old language) means roof tile (in correct modern Dutch: "dakpannen").


On 13.9.1944, taken by the RAF.


And here a military map of today.


Now I am going to locate the Zandweg. And see if there is also something called Vossenberg.
