Here we have two uniparts produced by our friends at Pittsburg High Voltage in Derry, PA. I regret that I cannot tell you the U-number but they are 3 3/4" high and the base is 5 1/8" wide. They have two inner skirts and unglazed pinholes. They are both near-mint with no discernible damage. I could describe the glaze color as "rich mahogany brown" or some such nonsense, but they are just a boring dark brown. They both have production dates incuse marked into the top firing rest. The one on the right says JAN 4 ANS and the one on the left DEC 15 1913. Buy them now and you'll have almost four months to plan an elaborate 101st birthday party for that one, which will confirm your family's long-held suspicion that you have, in fact, totally slipped over the edge. My price is $40 which includes Priority Mail shipping which will be in excess of $17. I can only accept PayPal for this sale.
