Mary has her father's vehicle registration from 1925. This states that Michael owned a 1921 Overland. Its Pennsylvania license number was 573413. Its "Engine No" was 140702 and its "MTg. No" (serial or chassis number) was 138464. The registration also states that the vehicle had 19 horsepower and a seating capacity of 10.
The chassis in Michael's car was an "Overland Model 4." The Overland Model 4 had serial numbers from 126926 to 174819 in 1921. The basic body styles for the Overland Model 4 in 1921 were the Touring, Roadster, Coupe and Sedan. In addition to these four styles, the Model 4 was also sold in several variations as truck or truck-like commercial and semi-commercial vehicles. These versions were not made in their entirety by Overland, however. Rather, Overland chassis' were shipped to the Martin-Perry Body Co. for completion. One Martin-Perry body was called the "No. 168 Combination Depot and Country Club Body." The Combination Depot and Country Club Body had a canvas top and would hold 6 persons. It had wooden sides and curtains with celluloid windows that rolled down from the top and snapped into the railing on the body. These aspects confirm well to Mary's description. No other 1921 Overland fits Mary's description so well. Thus, it is most likely that the car was a 1921 Overland Model 4 chassis fitted with a Martin-Perry number 168 Combination Depot and Country Club body.
Martin-Perry literature provides the following description of the Combination Depot and Country Club Body:
"Fancy passenger body with rear seats easily removable to convert it quickly for hauling freight. Especially popular for station service, at country resorts and among farmers.
Framework, posts, and windshield finished in natural wood. Small panels finished in walnut stain. Seats upholstered in brown artificial leather with soft spring cushions. Brown drop curtain all around for bad weather. Center seat folds to admit passengers to rear seat. Two rear seats are removable so that the body is easily converted for general hauling. Lights in curtain are constructed so that the curtains are storm-proof.
Regular Equipment No 168 - Windshield; three seats as shown; brown roll-up curtains with big lights; drop end-gate with chains, covered with leather; spring cushions; toe boards; bolts for attaching body to chassis."The picture here show the number 168 Martin-Perry body. It does not, however, appear to be fitted to an Overland chassis. The Overland chassis had an engine hood of somewhat more horizontal design.
This information was obtained through the help of E. Louise Pruitt, librarian at the WPKR - Willys-Overland-Knight Registry - "an organization interested in the preservation and restoration of vehicles powered by sleeve valve engines or the related family of Willys-Overland vehicles from 1903-1942"
