Would think the boiler sightglass end should be at the firebox door/burner end...
Otherwise it´s as logic would dictate, if solely comparing to the 75 mk.I.
Personally i think that it might just as well be, that the 35-A in fact was intended to stay as any other 35, only with heater/insulation swapped out for ventilation holes/burner.
The 35 version available in the late 50´s, was already then an older well known model, and taking those parts away would alter the detailing/look quite a bit.
That would leave Jensen with two very different looking engines, carrying the same modelnumber at the same time...would have been a first for them, as far as i can recall.
Anyway, all speculative until some proper documentation turns up. Deliberately say documentation, as it wouldn´t take much to fake one of the versions mentioned above.

In the late 1950's Jensen offered a #45-A.
This was an open flame alcohol fired #45.
Anyone have a photo of this in the brochure you can post?
As far as i recall there is no picture of these in the catalogues, only a section of alcohol fired engines in the pricelist.
The 35-A mentioned by Gil, logically would have had the 75 mk.I firebox/burner, but would be very interesting to see the exact design of firebox/burner on the 45-A.
They (35-A, 45-A) are listed in some of the 1950's brochures.
Here is my mock up of what we believe a 35-A should look like.

An interesting thread.
I agree with Jensen protecting its IP. Any patents probably expired years ago (I did a Google Patent Search and didn't find any), but Jensen certainly has the right to protect its trademarks and copyrights.
I suspect that the designer will be receiving a Cease & Desist letter soon. I am not sure why they don't pursue royalty agreements with other builders or joint ventures.
What I worry about with Jensen is that they have lost their "thirst for innovation" and they don't seem to have any interest in anything new (which is usually a death sentence for most family owned businesses).
I feel like we are watching the founder's legacy whither away with the second/third generation (which is not uncommon with family owned businesses which rarely are successful beyond the Founder/Patriarch).
I hope I am wrong. They have a loyal fan base here, for sure.

Sweet!

We have never seen one. The only evidence so far is that they are listed in the Jensen catalog brochure as was the #35-A.
Interesting, another "holy grail" offering to scour the nether regions of the world for. :)

Wow! Neat idea, but too much tooling to be made to have that as a product. It's almost like it would be an esbit fired 45?
-
What if Jensen decided they wanted to take his concept and just run with it...?
(make it their own 85V)
I would certainly buy at least one.
I suppose if this fella wanted to sell his intellectual property it would be okay, it does work both ways doesn't it ? I would suggest hiring him as a subcontractor , he/she obviously have skills they need very badly.

I don't see why there couldn't be a Mutual collaboration between this builder and the Jensen manufacturing company (should they both agree) , having visited the factory earlier this year , I could see a strong influence of Stuart Turner on Tom Sr's early work , correct me if I'm wrong, but didn't Jensen buy parts off of Wilesco. . Lineshafts , base pans....etc for "their" - engines ?
-
Well....it looks pretty good.
Needs to modify a few things for the sake of the Jensen name.
I agree .
I am but a simple neanderthal steamist, yet even I can see potential for trademark/logo infringement. But if the brandname/logo/trademark is not involved , where is the harm ? Please tell me if this is also an issue of patent infringement.
Hypothetically, if a person buys a steam engine, and would subsequently nickel plate it , would the buyer therefore not be allowed to resell the item under the ‘first sale doctrine’.
Excuse me for asking , but all this talk of counsels and legal options has me a bit confused.
-
Having just spoken to this user, as well as a couple of other users with similar ideas, I think (HOPE) they finally understands that as sweet as an idea for an unauthorized pseudo Jensen might seem , they will not be allowed by Jensen to offer it for sale. The Jensen family has already scheduled discussions with counsel, concerning potential legal options, should these problems persist.
Just as it should be!

Yeah I know first hand how it goes using the NAME. Neat looking engine but I'm like Bruce the cylinder mount looks realy light weight to me.
-
It would be great to have a good looking vertical that held up better than the lovely Wilesco D455. I would buy it for under $200.

He also mentioned working smokestack, so not only is he modifying/flaring out the bottom of the boiler, but I imagine he's also taking about adding a center flue through the boiler.
-
I'm trying to figure out how he's going to make any money at $120 with all the customizations??
Kind of my thoughts as well Nick , I don't believe he could make them for that, & Yes ...we all know that Cedge would come down hard on that (most likely) & I also thought that it would be a neat new product for Jensen as they aren't doing anything new currently. I give him credit for creating something interesting. ;)
the weak parts are the flywheel & piston assembly bracketry, be really nice if they were cast.
-
He even went as far as to show the Jensen Model tag with their address on it. In the last computer image on the left.
-
Neat engine but I agree, Jensen would be crazy to sell parts to a competitor but maybe this would give them an idea for a new model!

Yep, a pretty cool looking engine and an interesting concept, but he definitely needs to lose any direct Jensen references before attempting to market such an animal. It may be okay to state that he is using some Jensen stock parts, though even that may cause trouble, as I can't imagine Jensen would be any too happy selling parts to somebody who is looking to compete with them on the sales of finished engines.
-
In a New York minute , it'd be neat if Jensen made this. ;)
-
Seen this pop up on one of the facebook groups. I've let him know that it's not a good idea being Jensen is still in business, but it sure is a neat looking engine!
I see he's edited the description from my original screenshot to:
Hello everyone, I was thinking about building a VERY simple upright engine using some existing Jensen parts. The idea is to make an affordable upright style engine with adjustable throttle control. Also to bring back some nostalgic features like sight glass and actual working smokestacks. Would you buy something like this if the price is 120.00 USD? I appreciate if you guys could share with me your thoughts. Thank you.
