Here we have four porcelain uni-parts in four different colors. I apologize for not knowing the U-numbers for these but I will provide the measurements. Mr. Blue is 3 3/8" high by 3 1/4"" wide. He has an incuse marking on top of the dome consisting of the Westinghouse logo, an illegible letter, and a 7 and a 4. He has a very small glaze nick on the bottom of the skirt and a glazed-over chip on the wire groove. Mr. Red comes from England and is 4 5/8" tall and 2 3/4" wide. He has the Bullers logo incuse on the unglazed top, with the year 1961. He has a triangle shape chip out of the inner skirt. The red glaze is slightly faded on one side and brighter on the other, the photo shows the bright side. Mr. Green is 3 5/8" high and 3 3/8" wide and unmarked. The green glaze has reddish-brown highlights. There is a 1/2" by 1/8" scrape on the lower edge of the outer skirt. Finally, Mr. Yellow is 3 5/8" tall by 3 5/8" wide and unmarked. He has a shallow 1/4" chip on the inner skirt. This group of four is priced at $40 and I pay the Priority Mail shipping.
