This engine was found in a small rural antique shop.
The shop owner was nearly as curious about this engine as I was. After coming
to an agreement on a price, she insisted we test it before I left. Although
the lamp post was intact, someone had removed the entire generator set, the
steam line was bent and twisted and leaked badly. The Generator had long
ago been removed from the engine, probably by someone wanting to salvage
the magnet.
To our surprise, the dusty little engine ran smoothly as it covered her desk
top with water. She laughed and ran for towels as the exhaust soaked her
papers . She still asks about "Her Engine" when I drop in. |

Having a working steam engine was enough for several
years before I decided to attempt repairs. None of the hobby shops I asked
seem to know if Jensen was still in business, so I began a search on the
Internet. In short order, I found mention of them in a newsgroup which seemed
to indicate they were indeed still around. A quick check with directory
assistance and I was soon speaking with John Foskett at Jensen.
This conversation lead to the creation of the Jensen Web Site. Later, when
John came to visit, he took this engine with him to the factory in Jeannette
PA. Before beginning restoration, Tom Jr. asked if he could experiment with
installing a late model generator on the old style base since no original
magnets were available. Once completed, Tom Jr. certified this as a prototype
and documented it as a one of a kind factory experimental engine design. |

Unfortunately the law of unintended
consequences entered the picture. The
idea behind attempting to install the
more modern style magnet was to test
the feasibility of reintroducing this
much requested Jensen engine to the
product line. Upon completion the job
it was determined that the reintroduction
of this configuration would be too time
consuming and the idea was rejected.
Thus, this became the engine that officially
killed the classic Jensen model 10 design
for good.
