I've looked for hours on the internet and was able to identify the mark as being from the Webster Company. But I can't figure out what it is that I have or what it is used for. I've found picture of things with identical patterns, but none of them a capped end or the knob on mine. Any help would be appreciated, it's getting pretty frustrating looking on end without finding anything useful.
It is 1 and 7/8 inches tall and has a diameter of 1 inch. Thank you for your help.
