You are biddng on an old antique barometer. This vintage atmospheric pressure instrument is not marked with a maker. The glass face is about 3 5/8 inches wide and the base is 7 1/2 inches wide. I do not know if it works or not. I dont think it changes much with the weather but i have not been keeping track of it. International sellers must contact me first before paying via pay pal. International buyers please contact me first before paying. This is a hobby for me. Note that Standard Post can easily take a week or more to deliver, especially if you are on the opposite side of our country. It is sometimes off from what the Post Office actually charges me by up to a dollar or more. I will work with you to resolve questions and issues.
