Mack A/C and racecar

[Lmackattack]

Some interesting things in this pic if you look close. I sent it off to a friend that is a race car historian to see if he can give clue to the year of the race car in the photo.

 

Regarding the Mack AC I cant pin point the year of the truck as it has some odd features.

1) its in front of the International motor Co building but the truck says MACK

2) square fenders on the AC. most were rounded

3) screen mesh on the hood. most were louvered

4) hood looks more rounded than a standard AC hood

5) no side louvers for the radiator. its sides are flush with the cab cowl

That truck was one of the prototypes to the ac. Circa 1915ish. Taken outside the Mack building in Long Island by the looks of it

The International Motor Co was a holding corporation for the Mack Bros. Motor Car Company and the Saurer Motor Company. 

It had no relationship with International Trucks.

The logo on the front of a Bulldog hood is a stylized IM for International Motor.

Looks like even the car is chain driven. Very interesting picture thanks for sharing.

As ekennedy 21 pointed out, AC Mack E2 was a 3 1/2 ton and one of two experimental trucks that were built at the 64th street plant in the winter of 1915.  August 7, 1915 the truck left NY city in a military convoy of 15 trucks to Plattsburg, N Y.  It pulled a 3 inch gun as well as other guns, thousands of rounds of ammo and 30 men.  John Montville's excellent book "Bulldog" has pictures and more description of this truck and this event on page 22-23.  There are pictures of several different hood styles and lovers that were tried.  If you have interest in early Macks, get John's books.  His first was called Mack, and came out around 1974, and Bulldog  came  out around 1979. They show up for sale on eBay.  GREAT books!  Credit to Mr. Montville  for the above info.
