I don't think I saw the rolling block Waterman (sorry, I don't know your first name), but I was unfortunately quite rushed when I was there.  I was at the base on business and stopped by at the end of the day for a couple hours.  I'll take a look at my pictures and see if I have one that shows it.  I didn't see the entire place, but just hit the areas I was most interested, which was up through WWII.  I'm certain that if the USMC used them, then they were there somewhere!

On another note, I am ex US Navy.  I've been to the US Navy Museum in Washington, and I wish it was even half as big and involved as the USMC Museum.  The USMC Museum only opened a few years ago, but it is pretty impressive!  In 2015, the USS Ranger Museum is scheduled to open in Portland Oregon (providing they get the necessary funding donated).  I served on the USS Ranger CV-61 from 1987 to 1991.  I sure hope that museum is impressive!
