Nice and interesting. The "30" on right upper corner are grams written by T&T post clerk?
Thank you for the question. Inspecting dozens of covers disinfected at Boian I did not find any pattern. It looks that the letters were punch-hole in a quite chaotic way. Distances between the holes may vary from 2, 3 cm to 5, 6 cm on one letter.
The holes have a diameter of 1 mm. It is possible that they had an paddle which during the time needed repairs.
Fully prepaid letter sent on February 16, 1856 from Botoshani, Moldavia to Coeln (Koln Cologne), Kingdom of Prussia. The letter was sent with the Austrian post in the last period of the Crimean war. It was charged at Botoshani 12 kreutzer. The Austro-German Postal Union of 1850 and an extended Union Treaty was drawn up to operate from 1st July 1852 allow the Austrians to charge for the North Germany three silbergroschen for a distance over 20 German miles (aprox. 150 km). The nine kreuzer were charged for the Austrian transit. Route: Botoshani - Czernowitz - Krakov - Myslowitz - Coeln. Disinfection performed at Boian.
Pre paid letter sent from Galatz on May 1, 1845 to Genoa with the Austrian post. Double disinfection. First one was done at Galatz. A rectangular cachet with the dimensions 59x8.5 mm and reading "SAU CURATAT" lit. it has been clean" Type I. In the future I shell show the second type. From Galatz the letter passed thru Iassy and Boian quarantine where it was disinfected again and inscribed RN 36. Finally it was received in Genoa on May 10. It was charged 29 kreuzer.

It is important to note that this is a quite rare letter. Only a few pre-paid letters are known sent with Austrian Post from Moldavia to Sardinia.
Here it was charged 10 kr. C.M. till the Austria-Moldavia border and 19 kr. including the amount to be paid to Sardinian Post. The tariff of April 1, 1844 was used.
From the 19 kr, 7 kr. were paid to Sardinian Post for transport to Rayon 3 in which Genoa was located.
In an article published in Pratique volume xxx, (2005), number 3 page 87, Denis Vandervelde wrote an article about a remarkable envelope from Andy Chung collection. The envelope has a cachet reading "DISINFETTATO/SANITA MA*BRINDISI". Denis explained the reason why it is spelling "disinfettata" instead of "disinfettata". Now I present an envelope dated October 20, 1873 sent from Messina to Corfu. It was routed via Brindisi where was disinfected. The cachet reads "DISINFETTATA/SANITA MA-BRINDISI". I will be happy to hear other collectors opinion. These cachets are original or fake?
I add a scan of the article Denis wrote.
