Welcome, and although I'm not a SEABEE, I have made quite a few marking sets for SEABEE trucks. Somewhere I used to have quite a few pics of M715's in original SEABEE markings. Here is a link to my SEABEE marking page, http://www.deltateamdecals.com/seabees.html I got my SEABEE logo from a former SEABEE who brought home an original stencil in his gear and allowed me the opportunity to scan it and make copies in the decal program.
