Hope I do this right-I found this out in my yard, near an old barn foundation where stuff just keeps surfacing. It’s pretty corroded and I can’t see what is beneath the glass, so there is no clue what it’s function might be. It’s heavy for its size-around 2 1/2 lbs. Any ideas?
You know, we did wonder if it came off a truck..in the not to far off vicinity of this item, and the foundation, I found an old iron bumper jack. We thought maybe they used to park vehicles back there
