sorry not sure where to post this but I got on ebay 3 german signs for 1 each as none else bidded:

WW2 WWII ERA METAL SIGN DY97 GERMAN WAR RELIC? GERMANY? on eBay (end time 11-Jun-11 18:30:23 BST)

WW2 WWII ERA METAL SIGN DY38 GERMAN WAR RELIC? GERMANY? on eBay (end time 11-Jun-11 18:40:14 BST)

WW2 WWII ERA METAL SIGN DY525 GERMAN WAR RELIC?GERMANY? on eBay (end time 11-Jun-11 18:35:41 BST)

they were quirky for me so why not I thought. but no idea what they were for? seller says his grandad gave him them from germany after the war and his grandad worked for RAF, these are german bunker signs? or runway signs? honestly no clue any help?

thx
