Interesting developments - no information about Thor from the Norwegian Resistance Museum, but I wasn't expecting anything about him from them. I will go there tomorrow to review books/documents in their library, and to hopefully speak to a librarian about other bankers who might have been recruited to work for the resistance.

I did manage to walk to the Palace and found Oscarsgt., northeast of the Palace, where I located the apartment building that my great-grandmother Hilda lived in after her husband died in 1911. Thor lived with his mother here for a few years before his fateful move to Hammerfest in 1940-41.
