Here is another group from my collection, porcelain styles that appear to have been produced to compete with glass tolls. From left to right: Top: U-106, U-106, U-114, U-110, U-113, U-113. Bottom: U-108, U-108, U-105, U-105, U-105. All are unmarked. The U-108 are dry process. About half of these were in my original collection dating to the late seventies.
