I bought this on eBay for less than $100 including shipping. I wanted a cheaper one to attempt my first full restoration of an older Jensen. More to come.....

I also noticed that the screws on the sight glass have a “JS” logo inside a diamond. I don’t have these on any of my other Jensen Engines.

I've never seen anything there other that slotted screw heads, but those are hex bolts. Hope they carry the correct thread so that you're not dealing with that issue.
Lovely engine with the heavy cast flywheel, I'd say you got a bargain to work your resto on!
Hope it's all there and serviceable so that there are no bad surprises.
Nice Score!!!
Looking forward to how this goes. I am concerned however if those sight glass hex bolts used a different thread and are jammed in place. Fixable, but a hassle for sure.
For $100 to the door, you got a great deal.

Great price for a restoration project.
Can't wait to see what you do with this one Charlie

You've easily got $100 worth of parts there
Looking forward to your restoration as I need to learn the process to use on a few I have - hope you're lucky on the sightglass bolts and they aren't a problem.
An excellent piece for restoration, and well bought for that price! Keep us up to date on progress, and procedures! I've never mucked around with restoring a Jensen and am curious to see any pitfalls as I have an early No 5 waiting to be addressed.

I took them out this morning. They are the correct thread, not homemade and look like all my other Jensen sight glass bolts other than the hex heads with the JS logo. Soaking in vinegar now. Pretty cool.

Thanks Benny. It is all disassembled and I have been cleaning the individual parts. The plinth has been cleaned and conditioned with some polish made for antiques. I have ordered new springs for the reverser linkage from Jensen. I will Test the heater in the morning.
Please post some pictures of the bolts Charlie, never seen them on a Jensen, but you never know...

interesting banjo screws Charlie, I believe that somebody just got a nice JS Diamond logo bolt and modified them himself, I would be curious to know if they are made of steel or brass ?
Steel. They stuck to a magnet. The pictures are after a soaking in vinegar overnight and some buffing with the dremel (until the battery on it died). They are now soaking in Ballistol. I would like to reuse them if possible.
The Firebox housing doesn’t need a respray and the heater is functioning. So, I am not going to drill out the rivets on the boiler.
More to come.....
