Every so often, you will find something interesting that was hidden for a very long time... Recently, I bought items from the ex Zorić collection where there was also a cover with stamps with additional "T" overprints. Most probably a private "experiment", however, it looks like that cover was actually traveled.
1944 Šibenik, local provisional issue, registered letter, franked with stamps with additional "T" overprint, sent loco Šibenik (21.III.44).
Stamps enlarged.
