The photos show everything. Not sure the age, I believe it is relatively vintage, as you may be able to tell. This auction is for one final. I have several available. They are in the same condition as the photos show. There is surface rust, but I am assuming whoever purchases these will be refurbishing /repainting them to suit their needs. You can see the measurements, the base measures approximately 1-1/8 inch square, and the opening on the bottom is approximately 7/8 inch. These measurements are approximate, as close as I can figure. Not a whole lot to add to the photos, they are the description and they show the condition. THIS WILL SHIP USING UPS, FEDEX OR USPS, WHICHEVER I SELECT AT TIME OF SHIPPING. Offers will be considered for multiple purchases only.
