Don't forget the Lycoming powered mighty Checker Marathon. Lot of

running around with Continentals also.

At one time I owned a early Checker Marathon which had been powered
with a Continental flathead six and had a Buick V6 when I bought it.
But I am pretty sure Lyc did not build any industrial/vehicle engines
after WWII. Oliver/Cockshutt, I think, used Continentals along with
dozens of cars, light trucks, (Jeep used a Continental flathead at one
time), Hobart welders, gen sets, Zambonis-they were very popular and
all the ag and forklift vendors still support (most of) them. But to
my knowledge Lycoming cars were limited to the Auburn/Cord/Duesenberg
family.

You are correct they were Continentals in the Checker.
