[1] Velie ads bragged they "produce every important part"[2] and were not simply assemblers, a lesson Ford had taught.

[3] In 1911 Velie introduced a truck line, and began making a proprietary four-cylinder engine, although some parts came from suppliers.

[3] The 1911 Velie 40 had a 334 cu in (5.47 L) 4.5 in × 5.25 in (114 mm × 133 mm) four-cylinder L-head four-stroke gasoline engine, fired by Splitdorf magneto, producing 40 hp (30 kW), mated to a Brown-Lipe sliding-gear transmission with three forward gears, and one reverse gear).

[3] Velie's Royal Sedan body had a raked "A" pillar, which gave its windshield a significant angle.

In March 1929 Willard Jr. died,[3] and Mono was sold to Phil Ball, a St. Louis businessman and one of the backers of Charles Lindbergh.
