More news, on PeriscopeFilm.com.
They now have access to the full series, including the OP on the toperdo tubes. They'll probably be released as they are scanned, formatted and printed, no particular order.
Now that nuts, like me, will have the info to do super, cutaway models, it can be taken it to the next level. The real crazies can do cutaways of such things as the diesels, hydraulic pumps, trim and drain pumps, torpedo tubes, etc., to put in their cutaway models.
Kind of like "The Next Step Beyond".
