Craig, When I was at the Academy, I served on the Protestant Chapel Color Guard (Started as Escort w/o rifle or sword of course and moved up to Lead with US flag). Cool as it is the only time the American flag is dipped. With my MOS (Public Affairs) and as a trained broadcaster (radio), I've been involved in a lot of ceremonies, parades, changes of command, retirements -- usually behind a mic but sometimes actually doing something. I was adjutant for a USMC Birthday Ball once so getting to do the sword manual in front of an audience who ALL knew the manual too and were judging me (that included my first drill instructor -- Dad!!) was fun. The most moving, incredible lifetime experience, though, was over the July 4th, 1994 weekend when we brought Cpl. Terry Hoffman, USMC home from Vietnam (KIA) and returned him to his family (both of his parents were still living). So I know what you mean!
I'm no Jimmy expert, but I think GMC called their version a "Jimmy" Whatever, it was beautiful. A really well done resto.
