I bought these today and have found them on P.45 of the 1937/38 Ankerglas Bernsdorf catalogue on glas-musterbuch.de. They are the No. 412 Halle pattern shown in three sizes, these are the 25cm. ones. They are really quite impressive, especially under UV, so the 30cm. ones must be even more so. Also pictured is a part set Renate pattern to compare the colour.
