Tecumseh H70 aftermarket piston ring direction

I have an H70 I got free, came with a new aftermarket piston, rod and rings. There are no instructions on the installation of the rings (rings were in a sealed package, not tapered with). The oil ring had no bevels, nor did it have the wavy inner ring I am accustomed to. So I put that on as is.

The two other 2 rings are different. One has a bevel on the outside, one has a bevel on the inside. Both only have one bevel.

Any ideas on the correct way to install?

Thanks

Update: Found a small diagram in with the other parts of a piston and and several different side views of rings, I guess this is a diagram for multiple piston types and found a pairing that I think will work
Top Ring: inside bevel faces up
2nd ring: outside bevel faces down

I guess I'm going with that unless someone else begs to differ.
