Solved by faksta, woodinsight and others: One More Day at the Races

[Allemano]

actually it should had been raced somewhere else..

[woodinsight]

#13 - this is how the Nedloh appeared 10 years later in 1976.
Note the alterations - in particular the re-routing of the exhaust system

[faksta]

actually it should had been raced somewhere else..

That is, in another country?

No.

[woodinsight]

#2 - Australian?

[Allemano]

Not an Aussie!

[woodinsight]

#2 - I think this was at one time raced by Bill Bowman and I'm not sure if he built it too.

This one was the car of another Bill, so, you guessed at least the right forename!

[woodinsight]

#2 - Lazer Formula Vee?

[woodinsight]

#20 - Formula Atlantic?

[Allemano]

Please be a little patient. Temporarily I've no access to my archive. Will check it tomorrow, but if I remember correctly it's a "no" to both.

[Allemano]

#2 - Lazer Formula Vee?

It's not the name I have.

#20 - Formula Atlantic?

According to my source it's an unsuccessful attempt for a particular race series, but not Formular Atlantic.

[woodinsight]

another guess for #2 - Wheeler?

I found a very similar car on the web but with no name unfortunately.
Still searching........

[Allemano]

#02 is not a Wheeler.

[woodinsight]

I have two more guesses for #2 - Quasar?

[Allemano]

come up with your second...
as it's not a Quasar.

will give a clue if your second guess is wrong either .

[faksta]

I've found a Vee built upon the same idea of high windscreen and side panels, and it is called Viper. Looks different, but maybe it is another evolution? I'd try.

[Allemano]

It's called after an animal, but not after a snake.


I'm a clue:

[woodinsight]

Lynx?

[Allemano]

Close, but no cigar..

I wasn't aware that there is a very similar car named after a similar species...  

[faksta]

And also raced by some Bill 

[Allemano]

Astonishing, isn't it?

[faksta]

It's a Caracal D from 1981! I thought it was a mere ten years younger...

Sorry woodinsight in case you've also found it with this hint.

Oh, and looks like it won a 1982 championship with Bill Noble at the wheel.

[Allemano]

Owned/driven by Bill Noble!
Right you are faksta!

[faksta]

Now with that #20... is it Formula B?
