Could there really be to much to know about the 315? Know one will ever know it all but some might know most if not enough. I donated my 315 book that was in draft form to CRRM to help if needed for the restoration of the 318. Can't wait to meet the new Librarian at the Robert W Richardson Library.
I must say those guys did a pretty good job on the 318 in the roundhouse at CRRM.
