I am a postal historian with interests in Austro-Hungarian shipping companies and mail carried/posted on board. One such item bears the cachet of S.S.Kelet / Fiume /M.K.T. (Magyar Kiralyi Tengerre). Allegedly this is the only known postal item from Kelet and it subsequently passed through the Austrian post office in Constantinople 6 March 1911.
Information on the eventual sinking of Kelet would be most interesting for me.
Thanks in advance,
John Pitts.
