Don't think you could run down a particular factory for these things - produced commonly, possibly with an eye to tourists. If you look in Ruth A. Forsythe "Made In Czechoslovakia" - page 10 (No. 21) there is a bright yellow example, same height and with marvered coloured chips around the bottom inch or so - not unattractive, and guess they made them in several colours, provided you only wanted them in yellows and oranges. See another one as per the attached picture. Some come with just a snapped and rough pontil mark, but obviously they come also with the country name on the base. According to Forsythe these type of wares all come from the period 1918 - 1938 - and were produced by the same artisans who originally made Bohemian, Moser and Austrian pieces - the idea being that these "bright colours brightened even the gloom of the Great Depression of the 1930's".
