The cachet "Geräuchert vom Contumaz-Amte / zu SEMLIN am ... (date)" of the quarantine station of Semlin is found on letters from 1832/33. There was also offered a letter of 1835 with this cachet at an auction but the date of the cachet was not clear visible so I'm not sure if 1835 is correct.
I noticed that there exist variants of this cachet. These cachets differ, among other things, that no, some or all words are in italics.

The attached photograph shows a letter written in Constantinople and sent to Triest with cachet "Geräuchert vom Contumaz-Amte / zu SEMLIN am 23. Nov. 1833".
I'm interested to see further letters with this cachet.
