Rich,
I have been coming across your name all over the place... well, all over the internet actually - sorta happens when one searches anything related to these old boats. Seems you have this talent for finding the perfect distractors from my schooling: patrol logs, manuals... I even caught myself trying to wrap my head around the theory of operation of a TDC. The latter is a good thing - I can justify a truce with my war on math long enough to attempt trigonometry once more.
Where do you keep finding these long forgotten things?
Mike
