FIDET and Czech Standard
As playing sets, two types stand out in recent Czech practice - a variation of Austrian style - mainly by FIDET company - and National Czech style - still made in handicraft form nowadays see here. Plus glass sets from Liberec - crystal and pressed glass - porcelain sets etc.
Czech playing set from the 30ies - all filials are separate pieces glued into cavities! Kings stand 89 mm - the white knights are replacements. Similar sets in simpler form are still being made today in handicraft - check here ....
Plastic Set from Czech(oslovaquia), in the traditional czech tournament style, made in 1989 according to the informative price sticker. All pieces are felted, they are very heavy (weighted?) and have no mold ridge. Each piece seems to be composed of several parts glued together.
The older wooden version is still being crafted today - check here....
