1930 did you use a Sunnen portable hone or a Sunnen fixed honing machine? I just squared up worn cylinders by 0.009 inch with a 4 stone rigid portable and it was a lot of work. My arms nearly dropped off. It was an 83 mm bore too, so smaller than a Model A.
All turned out great with new pistons expanded to match each bore, for correct clearance.
I did it for fun to see if it would work. I started with 220 grit stones. Next time I will start with 150 and plateau with 320, and it might go quicker with less shoulder damage (to me not the bores!)
