Where can you find any information about the 817th Ordnance Base Depot company in World War 2?

The 817th Ordnance Base Depot Company served in the following campaigns: Normandy and Northern France. Source: Dept of Army Pamphlet 672-1 "Unit Citation and Campaign Participation Credit Register" which was used by commanders to determine who was eligible to wear campaign ribbons from WW2 and Korea. That is all I have. Remember, there is always a possibilty that the unit changed its name or merged with other units.
