Name that Car 2

ok, this is just a car and driver photo.....

Bruce McLaren (L) and Chris Amon (R) ???

Driver(s) are right - how about the car??

Car-Mclaren M15-Offy
Year-1970

Phoenix has the second part of the puzzle. Phoenix, it is your turn unless you want to pass the turn to SoCalPVGuy since he got part 1.......

It's really odd to see Mario in an Essex-sponsored champ car. Essex sponsored Lotus F1 a year too late -- after Mario won the championship with JPS livery.

Great pic! It's interesting to see a car with a rear wing ahead of the rear wheels.

I'll try and see if I can insert a photo...
Here is an oldie...
Year, Driver, Track, and type of car (not mfgr. "-" Special)

I am gong to guess Duane Carter in a Levosky-Offy at Indy in 1951. It was the Belanger Special...

Chris that is such a good answer I almost hate to tell you 'wrong year' (my source says '52). Close enough for me, how did you find this one out, was it that easy ?

You are up for the next on !!!
