Pennsylvania played a significant role in the manufacturing of antique gas engines, particularly for oil field applications, showcasing notable companies such as Evans Mfg. Co in Butler, recognized for its robust 4-stroke designs from 1898 to 1940, and the Ball Engine, also from Butler, which was famed for its reliable 2-cycle engines. Other important manufacturers included the Erie Gas Engine Co, New Holland, especially the “hit-and-miss” types from the 1900s and various pioneers associated with the Coolspring Power Museum, an essential destination for exploring engines from brands like Miller of Springfield and large compressors.

Join us at the 2026 show to explore the esteemed legacy of the Pennsylvania built engines, a testament to innovation and engineering excellence.

If you have any of these types of antique engines, we invite you to bring them to our September show, where these workhorse engines educate our guests about the way life was lived centuries ago!

All models and exhibits are welcome.
