Dad asked if I wanted to help him help a friend get an old car running. The old car is shown below. 1916 Overland touring car, 4-cylinder. An engineering marvel. Chain drive generator, magneto ignition, an engine-mounted air pump (to pump the tires up if they went low), three forward speeds, with reverse (in 1916!!), oil flow meter in the cockpit. It was a pleasure to be part of it.
Oh, and the 550 was parked at the shop next door...
