I think "recto" just means "back-side" in Italian.

The OP has double posted this on the SSFG forum. I'm not going to repeat my answers here.

Actually, I think it means "right-side" as in the right side crank arm.

My university Italian classes are a long way behind me, but I'm pretty sure right and left in Italian are "destra" and "sinistra".

In any case, it has nothing to do with the chainring as far as specifications. And it's not the model name.

Those 151 Pistas are the best chainrings EVER. Super overbuilt, always run true, I can't wear them out, awesome.

Less known is that the Shimano 151 rings are nearly as good, and have a way cool forged construction. BITD I had Campy in the even numbers and Shimano in the odd numbers--just worked out that way.

You are just looking at the two sides of the same chainring. There is a rather wide shoulder on the inside, which does offset the teeth by about 1 mm to the inside. The total width of the chainring at the shoulder is about 7mm, however, the width elsewhere is about 3.6mm, which is the same as other brands.
