Hi Daniel,
Thanks for outlining that. I'll have to look at those plans again but from memory this cabin was converted to tourist. It certainly looks nicer than it was and I know much of Olympic's accommodation was greatly improved by 1928 and 1935.
I think the photo was taken on April 2nd 1931 -- you'll remember I outlined the details of the subsequent crossing on TRMA a few months back.
I didn't make a copy, but I might have printed one out.
Best regards,
Mark.
