are from (if you don't know) and if they were in some trade in 1891. It
covers modern day Hungary, parts of Austria, known as Burgenland, Slovakia,
Sub-Carpathia, western Romania (the historical Hungarian territory
Transylvania), the Banat area (now in Romania and Yugoslavia), the Bacska
(partly in Yugoslavia), parts of old Hungary's Zala County (now partly in
Croatia and Slovenia), parts of old Hungary's Vas County (now partly in
Slovenia) and in the above mentioned Burgenland.
