To find such rare exhibits, he especially focused on the engine collections in various well-known technology museums.<\/p>\n<p>One of these was the Coolspring Power Museum (CPM) in Coolspring, Pennsylvania, which had been established in 1985. The place turned out to be a veritable engine Eldorado: The museum boasted an extensive collection of engines from the USA and other countries. <\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mwm.net\/wp-content\/uploads\/2023\/06\/Unknown.jpeg\" alt=\"Benz &#038; Cie.

The great question: &#8220;How did this engine come to the USA, and what was its purpose?&#8221; The answer was readily available. He was also pleased to learn that the museum staff were planning to restore the engine.<\/p>\n<p>The number 21542 that appears on the company nameplate is a Benz factory number. The engine on display is a HoRo RI-24 high-pressure crude-oil engine manufactured by the Benz factory in Mannheim Neckarstadt. The first HoRo engines equipped with Prosper L&#8217;Orange&#8217;s prechamber system were delivered starting on September 4, 1920.
