1. Internet user: Please let me know your source of information about ALTMARK that you have shown with FRANKEN images. Are they one series vessels?

Both Altmark and Franken were same Dithmarschen class vessels specially designed for Kriegsmarine. Altmark was damaged but she has not sunk in 1940 in Norway. After torpedo attack she has been towed to Germany and after reparation renamed to UCKERMARK. She has sunk after explosion nearby Yokohama, Japan in 1942. 53 men lost thier lives. It goes with out saying that vessels in some part were diferent but no that much so we can't think of different constructions.
This information are taken from different sources which you may find on SOURCES page of our web-service.

2. Internet user: Is it true that "Kanonierka" is UJ 1102?

No. Wreck (WK 12) at pos'n 54 35,8'N 18 48,1'E is about 24 meters long vessel. UJ 1102 was over 50 meters long vessel so it can not be Kanonierka as it is described in some documents and articles.
