Here is a special one of a kind Jensen 50.

This engine was Tom Jensen Sr.'s own prototype test bed for the early 3 heater Jensen #50's.
It dates to the time Tom Sr. began lighter blue-green paint and copper clad sheet metal faux brick fireboxes and chimney stands.

When I first got it, I sent pictures to Tom Jensen Jr. and remembered it well sitting on his Dad's desk for about 6 months during the trials period before becoming part of regular production.

It uses the same 2 socket Bakelite plug in block that all #50's from the 1930's through this time used along with a large blanket heater on the underbelly of the boiler. Also there are 2 pigtails coming out of the chimney stand just as all earlier models had. Tom Sr. connected the blanket heater and the inside cartridge heater to the inboard plug. For this test bed, he used a left over #50 riveted boiler. The 2 ceramic cartridge heaters are identical to all those used from the 1930's through the latter 1960's when the #50 got 3 Hot Watt immersion heaters.

It is easily recognizable as the only copper brick fire boxed #50 with a riveted boiler, 2 plugs, and the center screws for the blanket heater in the lip at the top of the firebox.

The standard production #50's after this one had the same 3 heaters with the addition of a 3rd pigtail and a 3 socket Bakelite plug block. They were made this way until the introduction of the immersion heaters late 1960's.

Below are 2 videos of this engine getting a good workout to make those heaters do some meaningful work.

In the 2nd video I swapped the safety relief for one that will hold 30 psi plus.

Enjoy,

Gil

To cap off the Jensen #50 display in our GPU I will show one more video.

The engine is not mine. In my humble opinion it is the most special of all Jensen #50's

It is numbered X9641 by A.E.C - O.R.N.L. which stands for

Atomic Energy Commission - Oak Ridge National Lab

All experimental projects on the X-10 Graphite reactor had their main components assigned an "X" number.

This, of course, by far, the most important of all Jensen Steam Engines #50's.

Here is a video I posted to YouTube shortly after our visit to Oak Ridge. Many of you have already seen this but if you haven't, it worth a look.

Enjoy,

Gil

Thank you!

Here is an excerpt on Jensen Steam Engines from a PBS TV program that used some of my info and material for their program.

Completely gobsmacked by the beams, and that rare Jensen lineup ticked just about every box with me, so in short...

Some serious "candy" at your table Gil, thank you so much for sharing
