PEBBLE BEACH, Calif. — Call it lunacy, but a team of technicians worked feverishly for seven months to restore a 1917 Moon back to better-than-new condition for the big auto show here.

A what?

Moons were the product of a pair of brothers, Joseph and John Moon, who opened their auto plant in St. Louis in 1907, according to history of the 6-45 Roadster prepared the Pebble Beach Concours d’Elegance. By 1925, the Moon factory was making 7,500 cars a year, but it closed in 1930.

Stephen Plaster’s Moon is now resplendent with a stunning yellow paint job and red accents on the wheels. Plaster, of Lebanon, Mo., says he was attracted to the car partly because of its Show Me State beginnings.

“When I saw it, I said, ‘We need to have that car,'” he recalls. He says it was called a “cloverleaf roadster” and the only way to access the backseat was through the gap between the two front seats.

But what would become a like-new show car needed a full restoration and there was only seven months to complete it. Jared Coho, whose 4 Generations shop did the work, said the team worked right up until show time, having put on the final touches hours before display.

The hardest part of the lengthy restoration was the hickory wheels, which had 265 parts. They had to be taken apart, sanded, primed and painted, then reassembled. It “took us a month to do all the wheels,” Coho says.

The result was impressive. Plaster himself said he was pleased as he got his own first good look at the restored car.

“I didn’t hear it run until today,” Plaster says.
