Early 1950's Jensen #25 with heavy flywheel and reversing linkage.
It ran well, but with a lot of leaks that I repaired (mostly) on the fly, with Teflon washers on all the main joints. The lower sight glass banjo bolt has a broken thread and the hole it screws into the boiler end cap seems to have weak threads too, so it kept a slow drip up as the run progressed. A new banjo bolt with full threads will be required to complete this repair and stop the leak, but otherwise, it was a fine run!
