That's a Nuovo Record crankset. Strada just means road.
I polish my parts pretty much the same way Ray Dobbins does except that the really beat up parts get sanded before buffing. I use a quarter sheet Porter Cable sander and then I hand sand up to 400 grit and then I use super fine steel wool. My buffing wheel is mounted on a 16" drill press.
This crank was in really bad shape when I started:
Don't leave the oven cleaner on too long when you remove the anodizing or it will begin to eat the aluminum. you may have to treat the part more than once to get all of the anodizing off. You'll know all of the anodizing is gone when the part turns uniformly black.
