Answer To Mysterious Engine
Has this reader correctly identified a mysterious engine from a past issue?
The following letter was previously published in the June/July 2021 issue of Gas Engine Magazine.
Hello and hope you are doing well. I am a long-time subscriber to Gas Engine Magazine, but this may be the first time I’ve emailed. I found what I consider to be a unique engine I’d like to share. I snapped these pics in Joshua Tree National Park, just outside of Twentynine Palms, California. This engine is part of an old-time gold ore stamping mill that includes a shaker table. The hopper on this engine is unique, and the entire engine seems to be of heavy construction. I am wondering if this engine is native to California and these desert communities.

I think I have the answer to your question. It looks to be a small rock crusher used mostly in assay offices. At least half a dozen companies made them in San Francisco. Very few of the small ones had a builder’s name on them. I don’t know why. Almost all the larger crushers have the foundry’s name on them.
