finally, something fun to share... Farbs. Mattel / Hot Wheels was selling these in 1971, and Kellogs even had one if kids mailed away for it

the series was the brainchild of independent toy designer Eddy Goldfarb; the series was named after Goldfarb as tribute.

 While the series was manufactured by Mattel and feature wheels also used on Hot Wheels products these were not officially branded as Hot Wheels products.

It turns out, Eddy, was a WW2 submariner, a radar and sonar operator on the USS Batfish, SS 310 from 43 to 45! 

Eddy enlisted in 1942, and is the last surviving crewmember of the Batfish. In its seven war patrols, the Batfish is credited with sinking nine Japanese ships, including three Imperial Japanese Navy submarines in a 76-hour period, in February 1945 — a feat unsurpassed to this day 

AND Eddy is most famous for inventing the Yakity Yak Talking Teeth! (plus 795 other toys!)

One Farbs track set Mattel produced with the cars was actually a Kellogg's Cereal promotion featuring the Hy Gear model and a short piece of Hot Wheels track, along with a green plastic boot that would "kick" the car down the track. It was called the "Booter Booster Set".
