#55 Twin engine series is the result of an ambitious design and engineering project undertaken by Mr. Jensen in 1948. The complicated slide valve timing was solved, providing a power stroke every 1/4 turn of the flywheel, thus making the #55 self-starting with a very high RPM. The # 55 Twin Cylinder Steam Engine is a serious engine for the serious collector who demands the very best at an affordable investment. retail at jensensteamengines dot com is $529.95
