Any differences between?

[Ridenmy65]

I have two copies of Burgertime by Mattel. One is just like the pic on this site. Says it was made in sigapore. This cart is rather light like other Mattel carts that I have. The other one says it was made in the good ole U.S.A. in the same year 1982. The difference is this cart seems to weigh quite a bit more than the other.

 

I was just wondering if anyone knows of any differences between the two carts other than the label.

One is a blob style board, the other one uses real chips.
