Long time brother the castle is the one facing the train station up in middle of the hill. The item was found right on top of that hill.
I still think it is beer related to that old beer factory. Reason is because they has that same exact symbol painted on the side of their factory. t was torn down about 4 years ago, I am sure you drove right past it on the main road, all that stands there is a house on the hill now. However you can still access the old bunker through the ground level. I was in there back i 2002 and there was lots of smelting tools in there, sure it is still there.
That side of the hill you are talking about used to have big church related events, that beer was the main drink. Thats why I think it is part of that very old beer company. I will ask my wife the name of the firm when she comes home.
Now if you take your first left as you get in to the village, the beer factory would have been on your left corner, drive down about 200 meters and its the old Orphans home, can not miss it like houses 600 orphans, another 10 meters to the right is the other castle, currently an American owns and lives at that castle.
But what I am saying is all that ground there is really good ground for Celtic artifacts, old school NAZI stuff and lost of WW2 items. You get up on the hill and you will start seeing all the old fighting positions, they never took them away.
Now if you come back on the other side of the train tracks that stream is where the Gold Rush of 1800s started, still plenty gold in there, all fines.
Anyway, there are many bunkers back in those hills that just got buried and forgotten. Lots of nice stuff in them.
I got a German helmet.
