This gentleman drove a Maserati in the 1959 Aintree 200 but I can't seem to find out anything about him other than that he was Masten Gregory's brother-in-law.

Can anyone add anything?

[arttidesco]

Never heard of him before but he seems to have driven a variety of sports cars with varying degrees of success including a Maserati 300S.

[Jerry Entin]

Dale Duncan was a Kansas City-based commercial airline pilot. In the U.S. he raced various cars including his own Jaguars and Ferraris, as well as A.V. Dayton's Maserati 300S.

After his divorce he moved to Houston where he raced Ferraris for his friend Big Jim Hall.

Thank you, Gerry, that helps a lot. The Kansas City connection confirms, to a degree, the truth of the Masten connection.

I wonder if he is mentioned in Mike Cox's book on Masten.

[Tim Murray]

I wonder if he is mentioned in Mike Cox's book on Masten.

He is indeed, Barry. He apparently played a significant role in getting Masten involved in racing. There's also a great story about Dale and Masten winding up the local plod by fooling them into thinking that Masten was driving Dale's Allard through Kansas City (when he was banned from driving) and pouncing on him gleefully, only to find that the car was right-hand drive and being driven by Dale.

He also gets a passing mention in a number of earlier threads, including this gem from the 'On this day in motorsport history' thread:

January 24,

(etc)

1954, Dale Duncan puts out a fire in his Allard's engine compartment during the 1000 kilometer endurance race in Buenos Aires, Argentina, by urinating on it. His co-driver, Carroll Shelby,
had thrown the fire extinguisher out of the car to save weight. They would finish tenth. Shelby's driving skills were noticed by John Wyer, who would later hire him to drive for Aston Martin. (Typical Carroll...) Am I correct in finding that Maston Gregory shared the win in that Argentine 1000km event with Eugenio Castelloti and Luigi Musso?

Dale and Betty Duncan in 1955

When Dale Duncan wasn't flying for Braniff Airlines, he could often be found in the winner's circle, like here at Kansas City on September 1955. The car is A.V. Dayton's 4.5 Ferrari, the girl his wife Betty, who was the sister of Gregory's first wife.

The car is A.V. Dayton's 4.5 Ferrari

Wasn't that the car Gregory raced in Europe in 1954?

[Jerry Entin]

David:

It is the same Ferrari: the 4.5-liter 375MM, chassis 0370. Gregory sold it to A.V. Dayton, who sold it to A.D. Logan early in 1957. A.D. Logan sold it to Dean Knight later in 1957.

Any connection between A.V.Dayton and modern historic driver Duncan?

[Barry Boor]

I wondered that, too.

[Jerry Entin]

A.V. Dayton was an Oklahoma-based manufacturer of electrical and seismographic equipment for the oil and gas industry. We have no idea if he is in any way related to modern day driver Duncan Dayton.

[Barry Boor]

I guess that Masten's connections to Centro Sud in previous years paved the way for his brother-in-law to get the drive at Aintree.

Not surprising that he never got another.

[Tim Murray]

Sadly, there's no mention of Dale Duncan's Aintree drive in Totally Fearless.

It seems unlikely that there's any close family connection between A.V. and Duncan Dayton. According to this profile of Dayton, he grew up in Minneapolis, his father Ken being CEO of the retail empire now known as Target.

[Jerry Entin]

Unlike Gregory [who did not need one YET], Duncan had a regular day job. Any Formula One adventures in Europe must have taken place on vacation time and as a result, unlikely to be repeated.

Didn't Duncan test a 250F in Modena around that time?

[Jerry Entin]

And of course by early 1960 Dale Duncan ceased to be Masten Gregory's brother-in-law. That is when Luella Gregory filed for divorce claiming "extreme cruelty". She asked for the Kansas City family home, $500 per month in alimony, $1,000 per month in child support [four kids] and a half-interest in stock and other properties.

Not sure if all her demands were met, but Masten avoided visiting Kansas City for quite a while. At the time his annual income was estimated to be over $50,000 by Luella.

Haven't hard that, though it's perfectly believable
Perhaps he signed up for the Centro-Sud school?

[Jerry Entin]

Since Duncan raced a variety of competition cars for almost a decade, I doubt that he would have signed up for the Centro-Sud drivers school. I think it was the kind of visit that Lance Reventlow and Bruce Kessler paid in 1957, testing a number of the Trident cars. Maserati was always eager to please visitors from America.

Incidentally, Gordon Pennington went through the same thing while visiting Modena. He was invited to test a Maserati sportsracer with Bertocchi in the passenger seat.

Thank you, Jerry. Thank you, Jerry.

We certainly have catalogued Mr. Duncan's racing career. Let's hope anyone else searching for this driver comes upon this thread.

BTW, why is he not on Darren's F.1 Driver information list?

[David McKinney]

Is it limited to WDC drivers?

(Most website seem to be)

[Barry Boor]

Good point, David, but then he should have shown up in the Others section - but he doesn't.

With the older photos now lost from this site, I believe (but am not certain) that this is Dale Duncan in the Temple Buell Maserati 450S at Caracas 1957 - attended on left by Guarino 'Guerrino' Bertocchi, Maserati's long-time chief mechanic...and, as he would always emphatically assert, "the fastest man around the Modena track - Moss?  Fangio? Behra?

Nope, that is Masten Gregory, his family member by marriage, in the cockpit. Dale is the one leaning in, next to Bertocchi. Glad you spelled his nickname as Guerrino, as it should be spelled, unlike the version used by present day historians.

Edited by WINO, Yesterday, 21:49.

[WINO]

At Caracas in 1957 Duncan was assigned to be Gregory's co-driver, but since Masten overturned the Buell 470S on the second lap, Dale never got to drive the car in the race itself.

 

As for the nickname Guerrino, it was given to Bertocchi at a young age by his mom. It means little warrior, a reflection of being perceived as a very busy child.
