Too bad we're not in super spy agency territory regarding technology and the Internet, yet. It would be great if one day we could scan an image and then process that image into "digital bits." Then we could code the bits and run our coded "image" through what's available on the Internet to see what matches. Some day, perhaps. Calling James Bond's Q.
As for the item not being an automobie carriage case, well, that could or could not be, but not all automobile carriage vases looked alike. Not all were clear glass; some were red, blue, green, amber, etc. I'm still not convinced it isn't an auto vase.
And perhaps it is a vase of some sort that did sit inside some sort of holder - something Victorian. I am pretty sure it's not a rolling pin.
