The First Out Of The Factory?

 As we have posted before, Falk, Rumely and Olds engines were the featured gas engines at Rollag this year. Three Falks showed up and the 5 HP (Number 433) was the only one running. Two 3 HPs showed up. One had serial number 723.

The other 3 HP is a puzzle, and there is nobody we can ask. What was the first serial numbered 3 HP engine that left the factory? Manufacturers don't usually start with 1, but where do they start? Could 51 be the first Falk 3 HP engine to be sold? Possibly, maybe even a good bet, but we will never know. Seeing that low number was a thrill, though.
