[targhediferro]

Moon, 1924?

[Paul Jaray]

Not Moon.
Take the time to read carefully previous posts, not because Moon was already guessed but because it can save you quite a lot of time 

[targhediferro]

Sorry, it doesn't dipend on little or bigger typing...it's me that I was sleeping!
La Marne?

[Paul Jaray]

I think it's a long, long sleep you are in then 
There were at least 2 different La Marne, the French one (Brun et Forest, Chalons, Marne) and the American one (La Marne Motor Company, Cleveland, Ohio).
One was european (4-cyl) and the other was an Eight.
The puzzle car is not European and is a Six, as wrote before...

[targhediferro]

No, this time I was awake, as I found notice about a La Marne six from Canada...

[Paul Jaray]

Interesting...according to my sources, Anglo-American Motors Ltd in Trenton, Ontario was going to produce locally the Eight 85HP built by La Marne Motor Company from Cleveland but probably just one car was made there...was that a six?
Anyway is not La Marne (or Anglo-American Motors).

Let's try a different approach.  Does the word "Six" appear in the car's name?

[Paul Jaray]

I'd say yes.

Winther Six-61 from about 1922?

[Paul Jaray]

Not that...
The car is a XXXXXX Six, the maker was XXXXXX.
Don't count the Xs.
...and remember the only rule is also the only clue.

Masterbilt Six from about 1926?

[Paul Jaray]

Ok, not a Masterbilt Six.
