In the WWII era was there an organizational relationship between an "Engineer General Service Regiment" (EGSR) and a "Service Unit" ? I have items from both the 1303rd Engineering General Service Regiment and the [1303rd Service Unit][1]. Are these items part of the same "1303rd" organization? The 1303rd EGSR was a temporary bridge building unit that served under General Patton's Third Army in the push from Normandy to Germany in 1944/45. I don't have any information about the 1303rd Service Unit except that it was based in Camp Lee, Virginia in 1943.
