Solved -PJ358 - Dana 510A Sports Car

[Allemano]

Lorries, resp. trucks?

[Paul Jaray]

Harley-Davidson?

No H-D, but you are very close...(not to the solution of this puzzle, but to the type of vehicles)

Lorries, resp. trucks?

Wrong way...

[Allemano]

Scooters?

[Djetset]

Indian Motorcycles? (the motor bike make, not the country!)

[Amsterdam]

Or did they built trikes?

Or did they built trikes?

Yes!

Is this company still active?

[Paul Jaray]

I doubt that.

The photo looks like a scan from a book or magazine.
Is this taken from youre, most likely, impressive library? or is it also online??

[Djetset]

Not a product by L&K Trike Engineering?

This photo comes from an ad at the end of a magazine. It was featured in just 1 issue.
Looking for info about this obscure builder (there is everything, company's name, address, telephone number...) I found online different ads in some magazines of this very company selling Trikes, with 2 different names.
Not L&K Trike Engineering.

Is this comany full American of origin and uses only American components, or are there any forgein influances of any kind?

[Paul Jaray]

I have just these ads...
I can tell you that this car has got an aluminum body, a plexiglass dash and many options, including 4-6-8-cylinder engines.
If you had few $ to spend those days you could have a brochure and color prints.
The Trikes are a different story: they were sold in kit-form or turnkey.
In one ad, the company, the address and all the rest is the same of the puzzle car and the trikes are called in a certain way...in another ad, the way the trikes are described became the company name, still maintaining the same address, telephone number and so on...
Probably this may lead you to the (half) solution.

Is this a Sidewinder built by Sidewinder Street Rods, a division of Cobra Trikes, Jeffersonville, Indiana around 1988?

[Paul Jaray]

Not a Sidewinter and not built by Sidewinter or by Cobra trikes, but it cames from Jeffersonville few years before 1988!

[pnegyesi]

Ecstasy Trikes?

[Paul Jaray]

Not Ecstasy.
They are described according to a specific technical aspect...

[Paul Jaray]

Black hole?

[Paul Jaray]

I'm not an expert of trikes, but probably the ones made by this company have an unusual collocation of their engine...

[microcars]

I assume the vehicle in question has 4 wheels.  If so is it considered a "quadricycle"?

also- did this trike manufacturer previously make vehicles that were for road use or were they not intended for road use?

Not quadricycle, they were trykes. I was referring to the position of the engine that may be not that unusual but enough to be a motto of the company and later the name of it.
I have an ad of this car taken from a magazine.
Looking for info for this company, based in Jeffersonville, I found more ads: one of a tryke built by this company and one of the same tryke under the name used in the previous ad as a slogan but with the same address and telephone number.
This is all I know.

Dana automotive engineering ?

[Paul Jaray]

Locked for you...in the meantime, please, share what you know about!

Looking for ads for trikes in Jeffersonville I found this one.
