The helicopter in the 386 Rescue Vehicles set contains at least a dozen
inverse slopes and another 18 slopes. It also contains two interior corner
slopes. Not sure what those are called, but they create a 90 degree turn.
The 371 also contains then but in blue.
Smaller amounts of inverse slopes can also be seen in sets:
370
387

All the sets mentioned above were available by 1976. So they obviously
started using them right away.
