Every round engine I ever saw or worked on had an odd number of cylinders for each row. The total number of cylinders would be even in a double row engine like the PW R2800 CB16. On a PW 985 there are nine cylinders, similar to the R1340 seen on a lot of ag planes. The sikorsky S51 had a special R985 that was mounted flat with the scavage pump relocated.

Which brings up a good question - How did the oil scavenge system work when there were pistons on the "bottom" of the engine? How do you keep all the oil from the crank bearings and the piston crown oil cooling jets of the upper cylinders from pooling down there and overloading the oil rings?
I can see a catch pan inside the crankcase over the lower cylinders with a slot for the connecting rod to go through, but you still have to scavenge the excess oil that gets below that point.
Probably why the horizontally opposed and Vee designs won out...

I'll second the Hustler. I had a plastic model of it when I wer a yungin. It had little escape hatches on the top the fuselage
I used to fly from Oakland to Honolulu, in 11 hours. Prop. Go to bed, get up and at the break of dawn - fly 11 1/2 hours on to work. The killer part - the engine hum and sometimes an off balance in one with a harmonic setup. We were fed like pigs being fattened - no movies nothing. Books and magazines were it. Writing letters and talking helped some of the time.
Now it is a 3 or 4 hour trip for an afternoon and night.
I like the prop - and flew from 2 props (AA) (drove the flying tank C-47) liked the DC-8's and flew in a Connie once (charter). Flew the big and small jets as well.
Dad flew lots of different war birds. During and after the war. He liked the B36 for the sound and the B-52 for power. He was into Bomber Radar before being switched to missiles and space.
