1.2 How to use this document during the restoration and judging process

The judging process at MVPA events has not been very consistent during the history of the association. It has been difficult to strike a balance between the needs of the “purist” restorers and members who wish to use their vehicles for recreational purposes. In an attempt to strike a balance, the MVPA has sponsored two classes of judging. The Combat Class or Motor Pool Ready Class provides a an opportunity for recreational collectors to display their vehicles and to discuss their work with judges who may be able to provide input into questions of safety and authenticity. This document will not be used as the basis for judging the Motor Pool Ready class. The Factory Class exists so that members who are intent on restoring their vehicles to as delivered condition will have the opportunity to have their vehicles judged against any such standard that may exist. In the case of the GPW, this document is that standard.

Vehicles are judged against the standard, not against each other. This means that if no vehicle is entered which obtains a minimum number of points when judged against this standard, then no awards will be granted.

1.3 Reproduction parts

In recent years the supply of certain GPW parts in NOS or good used condition has dropped to the point of near unobtainability. In addition, stocks of certain early production parts were exhausted during WWII and have never been available to restorers. Because of these facts and to encourage a high degree of craftsmanship and ingenuity among restorers* , no points are deducted for reproduction parts that are indistinguishable from the original.

* The purpose of the policy on reproduction parts is to encourage vendors and individuals to do a better job when reproducing parts. Reproduction parts have always been necessary for any type of vehicle restoration, and these parts should be built as accurately as possible.

1.4 Policy on Accessories

Since the purpose of this document is to provide a standard describing the GPW as it left the factory no attempt is made to describe in detail the many accessories (mounted equipment) that may be properly installed on a GPW. In order not to penalize vehicles that have been restored to “as delivered” configuration, no additional points will be awarded for installed accessories. Conversely, points may be deducted for incorrect accessories or accessories not proper for the vehicle being displayed. No additional points are awarded for signs, mannequins, driver uniform or other displays not part of the vehicle being judged. *

* Vehicles modified for 12 volt operation will not be judged in the factory class, except for those built under contract W-374-ORD-4358

1.5 Disqualifications from judging

Vehicles submitted for judging in the factory class will be immediately disqualified if they fail to meet certain minimum standards. Grounds for disqualification include:

1. Safety hazard. Any conditions that in the opinion of the judges makes the vehicle unsafe for use on the road, or which produces a danger of fire are grounds for disqualification. This includes inoperative service or parking brake, defective steering or suspension components, fuel leaks, frayed or damaged wiring and unsafe tires. Features of the vehicle which were present in all vehicles when they were manufactured will not be used as a grounds for disqualification, for example lack of seat belts or turn signals.

2. Incorrect engine. All vehicles being presented for judging must include a Ford GPW engine, unless the owner can produce documentation showing that there is a reason-able chance that the vehicle left the factory with some other engine. Non-matching serial numbers will not be used as a grounds for disqualification, but will result in a significant reduction of points.

3. Improper body repairs. Repairs to body sheet metal should be indistinguishable from the surrounding sheet metal. Repairs which include visible pop-rivets, fiberglass cloth, plastic fillers, etc. are grounds for disqualification, even if the repairs are on the underside of the vehicle. Use of fiberglass body components will also result in disqualification.

4. Use of modern components. Use of components which were not available at the time of the vehicles construction is grounds for disqualification. This does include: modern plastic covered wiring, 12volt ignition systems and electric fuel pumps. It does not include: spark plugs, headlamps, tires or fuel filters. These items will result in a loss of points.

1.6 Concerning "f" marked parts

During the manufacturing history of the GPW, most of the component parts were at one time or another marked with some type of “Ford” identification. Most often this consisted of a script letter "f" although sometimes “Ford”, “GPW” or a block F were employed. Considering the wartime shortages that were common during the GPW’s production, it is likely that Ford may have employed many subcontractors to produce GPW components, as a result, it is not required that every part that might possibly be marked be present on a given GPW. Parts that are required to be marked are mentioned explicitly in the standard.

GPW tie rod ends are marked Ford (in script) U.S.A. The tie rod tubes are marked Ford (in script) U.S.A. or they can be marked GPW. The tie rod tubes clamp bolts should have a "C" or "RA" or blank heads on the bolt. It seems that 42 and 43 have the "C" bolts and after that they have RA bolts. Information on clamp bolt gathered on G503 and should be researched further. -Herb Tate

1.7 Changeover dates

Many of the dates listed for manufacturing changes in this document are intentionally vague. Unlike other vehicles, such as the Model “A” for which restoration standards have been produced, the GPW was produced during the wartime period of chronic materials shortages. GPWs were produced at 6* different plants during WWII and change orders were rarely synchronized between manufacturing facilities. The result is that in many cases, specific changes were accomplished only when existing stocks of component parts were exhausted. Varying supply channels for components resulted in vehicles rolling off the assembly line with components of one subcontractor followed by the next vehicle using parts from another supplier.

With the preceeding warning in mind, it is possible to use the changeover dates provided here when judging vehicles. By allowing a window of one or two months for changes to be accomplished, the judging process accounts for these variations. When a component differs from specified dates by more than 2 months, the owner should be asked to show evidence that the part is correct.
