Here is a white porcelain, crosstop-incuse U-923 F.M. LOCKE VICTOR, N.Y./PAT. MAY '89 MAY 22, '94 (marking number 2-2) with MANUFACTURED BY/IMPERIAL PORCELAIN WORKS/TRENTON, N.J. incuse on the skirt. There is a bruise/crack in the skirt at the Imperial label as shown, an open bubble at the base of the skirt of the other side, and some chipping/flaking to the corners and edges of the top. Hard to say whether some of that was from manufacture. The inner skirts are slightly out of round and otherwise perfect. For $10 plus postage, you won't be disappointed. (The color is true white, not cream as it appears in the middle photo with bad lighting.)
