Class 20F - Production Vehicles excluding Ford, 1940 - 45.

1941 Packard 110 DeLuxe convertible.

Beginning in 1937, revered luxury car builder, Packard, did the unthinkable and introduced a line of entry level cars. The idea was simply to increase sales volume, something the company needed in the post-Depression era. The entry level series was designated the "Six," because it featured an inline 6-cylinder engine, (the rest of Packard's products were powered by either an inline 8-cylinder or V12). In 1940 the Six line became the "110," which was written as "One-Ten."

Sales were strong and accounted more than half of all Packard sales in 1937. For 1941, One-Ten production is estimated to be around 34,700 car, which represents approx. 47% of Packard's total sales for the year.

From what I read, there are varying opinions on whether or not entry-level model production was the beginning of the end for Packard. Increased sales volume was necessary for the bottom line, especially in the wake of the Great Depression. But some believe Packard hurt its reputation as a superior luxury car maker by offering an entry level product.

Class 21 - Ford Production Vehicles, 1928 - 48.

You may have wondered why the previous Class 20 Production Vehicles classes were labeled as, "Excluding Fords." This is because Fords from 1928 - 48 have their own class: Class 21. The first four, Class 21A, 21B, 21C, and 21D, are devoted to the Ford Model A.

Class 21D - Ford Model A, closed vehicles, 1930 - 31.

1931 Ford Model A

Power comes from a 201 CID inline 4-cylinder engine that makes 40 hp.

Class 22B - Commercial Vehicles under 1 ton, 1928 - 42.

1929 Ford Model A pickup.

Even though I just said that the Ford Model A falls under Classes 21A - 21D, this Model A pickup falls under Class 22, which is for Commercial Vehicles. The AACA defines a Commercial Vehicle as any kind of truck or bus, but not a station wagon.

I don't know exactly how old the tires seen in the above photo actually are. But judging by the weather cracking, they've been around for a while.

Power comes from a 201 CID inline 4-cylinder engine that makes 40 hp.

Class 22B - Commercial Vehicles under 1 ton, 1928 - 42.

1936 Divco S.

The Detroit Industrial Vehicle Company was founded in 1926 by George Bacon. While working as the chief engineer for the Detroit Electric Vehicle Company, Bacon developed a milk delivery van in 1922. His design incorporated features unique to multi-stop delivery vans such as being able to drive the van from four different positions, (front, rear, and either running board).

Being the chief engineer for a company that manufactured electric cars, Bacon was well aware of the shortcomings of battery power, especially during the winter. He wanted to use a gasoline engine for his van, but management didn't like the idea.

Bacon decided to manufacture the van himself and founded Detroit Industrial Vehicle Company in 1926. Divco changed hands several times and operated under various names until it went bankrupt in 1986.

The first thing you notice about this van is that there is no driver's seat. This is because this van was designed to be driven from the standing position.

The photo above shows the two pedals near the floor of the van. The outboard pedal is the combination brake/clutch pedal. Pushing the pedal downward first engages the clutch, then the brake. The smaller inboard pedal is the accelerator.

Class 22C - Commercial Vehicles under 1 ton, 1943 - 66.

1955 Chevrolet 3100 Series pickup.

Chevrolet's Advance Design series of trucks debuted in late 1947 replacing the AK Series. This was the first major truck redesign following WWII. Production lasted through March 1955 when the all-new Task Force series was introduced. The "3100" series represented the half-ton light duty pickup.

Power comes from a 235 CID inline 6-cylinder engine that makes 123 hp.

This 1955 model represents the last of the Advance Design series.

The changeover to the new Task Force series took place beginning in March 1955. This means a 1955 Chevy pickup could be either series depending on production date.

Class 22C - Commercial Vehicles under 1 ton, 1943 - 66.

1950 GMC pickup.

Chevrolet Advance Design trucks were also marketed in GMC dealerships as the GMC New Design series.

Power comes from a 228 CID inline 6-cylinder engine that makes 96 hp.

I believe this engine is unique to GMC, which used its own line of inline 6-cylinder engines from 1939 - 1974.

Like so many others on this day, this GMC had beautiful paint.

Class 22C - Commercial Vehicles under 1 ton, 1943 - 66.

1950 Ford F1 pickup.

The first generation of the Ford F-Series pickup debuted for the 1948 model year and marked the debut of a platform specifically designed and engineered for truck use. Before that, the Ford pickup chassis was based on that of the contemporary Ford car. Truck models were designated F1 through F8 with each representing a different weight class. The F1 designation represents the light duty "half-ton" model.

Power comes from Ford's famous 239 CID 'Flathead' V8 that makes 100 hp.

First generation F-Series production ended in 1952 when it was replaced by the second generation F-Series. This also marked the changeover to the more familiar 3-digit model designations of F100, F250, F350, etc.

Class 22D - Commercial Vehicles 1 ton and over thru 1927.

1926 Ford Model TT.

The Ford Model TT was a one-ton commercial truck that was based on the Model T car chassis, but with heavier duty components.

Class 22D - Commercial Vehicles 1 ton and over thru 1927.

1918 Ford Model TT.

The Model TT was powered by the same 177 CID inline 4-cylinder engine that makes 20 hp that was used in the Model T cars. The trucks were known for being very durable, but painfully slow. Several sources I examined list the Model TT's top speed at around 20 mph.

This truck still had solid rubber rear tires that looked like they have been there for a while.

Class 22I - Military Vehicles thru 1998.

1952 Willys-Overland M38 Jeep.

The Willys M38, also known as the Willys MC, is the military version of the contemporary Jeep CJ-3A. The MC entered service in 1950 and remained in production until it was succeeded by the M38A1, or Willys MD, in 1952. A total of 45,473 were produced.

A number of changes were made to the MB design for the MC. The windshield was still foldable like that on the MB, but was now one piece.

The axe and shovel "Pioneer Tools" seen in the photo above were moved to the passenger's side of the Jeep, having previously been mounted on the driver's side on the MB.

Power comes from a 134 CID inline 4-cylinder "Go Devil" engine that makes 51 hp.

My guess is that the spark plug wires look somewhat unusual because the electrical system was waterproof. Also of note is that this Jeep uses 24 volts instead of the typical 12 volts.

Class 24A - Documented Competition Vehicles, oval, straight, or circular track thru 1998.

1970 Eagle Indy car.

Designer Tony Southgate joined Dan Gurney's All American Racing (AAR) team in late 1967, and designed the "Santa Anna" Eagle Gurney would pilot to 2nd place in the 1969 Indianapolis 500. For 1970 season, the Santa Anna chassis was redesigned by Len Terry. AAR developed and built six of the redesigned Eagle chassis for the 1970 Indy Car season. Two of them were for Gurney's own AAR team (chassis 801 and 805), and the other four were for other teams.

If I interpret information I found on oldracingcars.com correctly, this car is thought to be chassis number 805, the second AAR team car. However, this hasn't been confirmed yet as parts of the car's history are still a mystery.
