I have been scanning some manuals that I have and sending them over to Nick.  This Manual is for the RDZ from 1950 NAVSHIPS 91331.  What I found interesting was the cartoons throughout the manual.  It says it was prepared by Philco they are pretty funny.  Here is the link to the Publication (Which will probably be on Nicks Page also if he doesn’t have it already) Anyways  proper (Or improper radio repair via cartoons)
