472nd Engineer Maintenance Company

[6th airborne]

I have been looking for any information on the 472nd engineer maintenance company that my great uncle I think was a part of. The only scrap of evidenance is a letter from the CO of the 472nd engineer maintenance company (Capt. Burton N. Pinkham) to the CO of the 973rd engineer maintenance company declaring that my uncle was entitled to a battle credit for his participation in the Guadalcanal campaign. I am trying to research his military history and the units he was in. So far I have found out he was in both the europian and pacific theaters. I am having a hard time tracking down any information on the unit he was in while in the pacific. He was associated with the army air force engineers as a mechanic fixing large construction equipment that built runways and airodromes. If any one out there has any information I would appreciate it. Thank you.
