3179 - Acadia Runabout?
If not can I have another useless clue please

54321 - Lancia Aprilia Serie II Cabriolet Pininfarina

New number 43210

[Paul Jaray]

I'm getting nowhere. Cobra Kit Car companies are virtually uncountable. Are there any more clues on offer?

You are right, but fortunately this one is not that known...it means that if you find a Cobra manufactuer, starting with A (near the very bottom of the A-named makers, but not Az), named after its builder, it's probably your guy.
Just to give you an idea, this maker is reported in 3 books of mine, ERA, for example, in 6.
I can say that it rymes with something He sure was looking for! (more or less)

Ron Ayers Classic Cars;  Simpsonville, SC?

Yes! +50
Which clue help you most?

[Paul Jaray]

Acadia Runabout?
If not can I have another useless clue please

54321 - Lancia Aprilia Serie II Cabriolet Pininfarina

New number 43210

Not Acadia. It's quite obscure, reported in just 1 book, later become the American importer of a better known French maker, if my list was in Greek, this one will be one of the 1st makers...active just in 1903.

81477:FORMULA 1 1964

63558 is a Mercury, and I hope it is Mercury(9).
74625 is a Peugeot.
81477 could be the R.E.-Alfa Romeo driven by Ray Reed (R.E. stood for Ray's Engineering)

[targhediferro]

I quit 20017 and 30017, too difficult for me.
May I have 50017, 60017 and 70017?

[pguillem]

This makers, starts with 'W' and it's the union of 2 surnames Wxxxx & Lxxxxxx. It's not a well documented maker and useful clues may be hard here.

The list of defunct manufacturers doesn't help.  May I have 100100 ?

[Paul Jaray]

They were WELCH & LAWSON.
100100:BMW 501 CABRIOLET mid 50s

[targhediferro]

I did three lucky numbers...let's continue the 17 line...80017, 90017, 100017, please.

82775: Requa 1912
101101: MODEL 77 SEDAN 48 HP 1936

I would be surprised, if 62596 weren't a Mercedes-Benz.
Are you sure that you haven't given the name away with #82775? There was a Requa European Motor Company of New York in 1912. Production is doubted.
101101 must be a Willys.

[pguillem]

They were WELCH & LAWSON.
100100:BMW 501 CABRIOLET mid 50s

WELCH & LAWSON : I never could have found it.  Google only shows pumps and woodworking machinery
100100: is it the Baur cabriolet ?

If I'm right, may I have 1151, 10151,100151 ? Thanks.
