Mine from 1975 have the tan roofs and the blue and yellow corner pieces.
The majority are the smooth red and white. I still have the canister
they came in! We didn’t have much money so I tried to take care of my
toys.
I have a set of the smooth sided American bricks. I received them in
1965 for Christmas. Much better than legos, they held together much
tighter. They still do!
