Marion - Thought you would like to see these photos taken from old Bulldozer manuals during WW2. A Seabees son sent them to me.

Thanks John. Posting them here for all to see. 


I found this one on Google:

The Library of Congress has four WW1 Engineer posters online digitally. The Universities of Oregon and Washington also have about 1/2 a dozen from the Spruce Production Division. The SPD was officially a Signal Corps unit, but in mission and MOS's assigned, they were Engineers.
