I'm no expert on hit-n-miss engines, but my Dad has quite a collection, mostly Fairbanks, so i'm a bit familiar with their operation.
I tell him that I only collect things i can ride on, not have to drag on the trailer
Seems that the IH engines rank high on the 'collectability' and sought after list. Good for you
Coolsprings PA, has a large spring show of hit-n-miss engines and a large collection of equipment on site. Terriffic show, i plan on going. Very interesting seeing the development of ignition systems from that period.
if the water tank and head is intact and not cracked, you're way ahead. and if you have the ignition mechanism, that's a large plus, they can get pricey.
