The TM 10 series were the early WWII tech manuals for the trucks. They are profusely illustrated, and have all information for rebuilding pretty much every system on the truck. They are great references to have on hand for restoring the early WWII trucks. They were superseded by the TM 9 series of manuals, which are good in their own way but don't have as much information as the earlier ones. The first number change is for a very specific reason- manuals in the army are numbered based on the branch of responsibility for the item described. Before 1942, the Quartermaster Corps had responsibility for vehicles. All Quartermaster manuals started with a 10 prefix. After 1942, the Ordnance Corps had responsibility for vehicles, and their manuals all were prefixed with a 9. Also good to know, the TM 10 series also had a corresponding TM 10 parts manual, which was usually one digit different from the maintenance manual.

The Ord 7,8,9 series were part of the Ordnance corps parts system. The Ord 9 was the standard nomenclature parts list. The Ord 9- SNL G502 is the standard parts manual for the Dodge WC51 series. The Ord 7 and Ord 8 were supporting documents- the Ord 8 as shown in the auction only lists the parts by part number and the amount which were supposed to be held by each unit. For example, you will find listed a part like a carburetor. Next to that part, in multiple columns, you will find a fraction or whole number underneath each column. The column headings will list the unit holding the truck, 1st, 2nd, and 3rd and higher echelons which supported that unit. The fraction was used like this- if the carburetor fraction was 1/6, and you had 6 trucks under your care, you carried 1 carburetor on hand to support those trucks. This was true for all the other levels- but they had different fractions depending on the number of trucks they supported. Also, some parts were not carried at the unit level- they were only for upper echelon maintenance or overhaul. In other words, a battalion with six trucks didn't carry a spare engine, but the upper echelon ordnance maintenance shop which supported 60 trucks carried a spare engine or two.

I only mention all this because the ORD 7 and 8 aren't really useful for restoration- the Ord 9 is. But they are nice to have to know how they managed maintenance in WWII.
