Daniel Woditsch sent me these photos of a Taylor wrist compass he found by metal detecting at Gossersweiler by Dahn, Germany. This would have been on the way to the Rhein river for the Americans, although I don’t know about any particular combat having taken place there.
The point however, is that Daniel opened the compass and found that the compass module inside of the bakelite housing is actually fully self-contained and it even still has all of its liquid. The bottom of the module is still clearly marked MAR 24 1944. I can only assume that other Taylor wrist compasses are dated likewise, but you can’t see it unless you’d pry open the casing.
His compass looks remarkably well preserved for having been under the ground for 75 years! It’s a great opportunity for us to see the inside for once.
