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. UNFORTUNATELY, DUE TO THE HEAVY WEIGHT OF THESE, COMBINED SHIPPING CANNOT BE OFFERED WITH THE TWO LOTS OF 20 AVAILABLE IN MY OTHER AUCTIONS.
