A very rare vertical air-cooled Erie engine, one of just two known to exist, in Kenny and Wendy Wolf's gas engine collection. Every part of the engine is original; parts were copied from this one to rebuild the only other Erie known of.

An early 1900s salesman’s sample Callahan engine with Goodson igniter, presumably one of a kind. The Wolfs paid more than they wanted to for the piece, but, as Kenny notes, “if you think you gave too much for a good piece today, just wait until tomorrow.”

It’s a quandary faced by every collector: What to keep, and what to sell?

Career antique gas engine collectors Kenny and Wendy Wolf have adopted a practical approach that helps them build their collection. “If we had six engines in the garage and found one we liked better than one of those,” Wendy muses, “we might sell or trade one to make room for something new. I think that’s a good way to do things. That way, we get to own an engine, but if we get tired of it, then it goes to another collector who’ll appreciate it and enjoy it.”

The sheer tonnage of old iron that’s passed through their hands over the years could break a back several times over. “I’ve had some of these engines for 35 to 40 years,” Kenny says. “The old story that ‘Wolf will sell anything’ isn’t always true. This is an odd thing to say, but you never want to look back: Always look ahead. I’ll be honest with you. If I still had every engine that I ever sold, it would cover 50 acres.”

Kenny says he’s always had an interest in mechanical things, but it began to ramp up about 40 years ago when he and Wendy and their children became regulars at the Tri-State Gas Engine & Tractor Assn. show at Portland, Ind. “We’d use our mad money to buy an engine,” Wendy recalls. “A couple of our daughters just grew up knowing about engines. We would buy almost anything; pretty soon we had a barn full of common engines.”
