Sets listed below are of Unknown origin.
If you know more, then please let me know...
This "travel" set was bought recently with the main reason that I have a travel set with exact the same pieces, which was bought in the Netherlands in 1948. See my Travel (Netherlands) page. Jaques did sell travel chess sets in a leather case with exactly the same pieces. The pieces must have been made by the same manufacturer, but unclear is who that is.
