Was doing some research for a new forum member and stumbled upon this page which lists a few dozen engineer units. I noticed they also had a reference for the 540th. Hmmmm!

Looks like you would have to contact this address and ask them how to obtain any of the listed materials on the page above. (I DO NOT currently know where these materials are currently kept. - Maybe it's at the university.)
