Here you can see the petticoats of the U-751 (Pittsburg?) - the middle skirt is not sloped outward but is vertical, proving that it is not the VERY similar glazewelded U-933. There was no ring of bubbles or gap, confirming it is not a classic-era piece but still, the design and glaze appear to be older than the 1930s - perhaps a very late Pittsburg / early Westinghouse piece. Also, note the remaining original black lacquer on the inside of the pin cone assembly.
