China stencils.
Glass and metal rhinestones. There is a BIG pile of plastic rhinestones for another post.An now to the what's-it. I found this at The Bins the other day. There is a mercury thermometer mounted in the groove and it is lined with metal. The cup at the bottom is brass.
There is a hole at the top that could be for hanging it up or maybe for a string if you needed to drop it in to a pipe or something.
The whole thing is about a foot long. Since it has the cup on the bottom I am thinking it was to dip up liquid and check the temperature. Has anyone seen this before?? Any ideas??
