I'm sure your search has shown this?
I'm not sure how reliable this company is, I do know it is hard to find pistons for pre-80 PE's.

The vintage piston supplier's I know of.
Neither lists your model. 

Can you (or a good machinist) modify another piston? I'm not sure.

I counted myself very lucky to find a NOS 0.50mm over Suzuki piston and rings from a dealership in Texas, and had it sent to me in Canada. In your search, know that the original part# for a standard piston 12110-41502, which was superseded by 12110-41503. A set of rings and wrist pin circlips (not the wrist pin) is part# 12110-41500. Assuming your cylinder is still in great shape and doesn't need boring, those part numbers will work. You may need to bore the cylinder because of wear/damage, or because you can't find a standard-sized piston and rings. In that case, add "-025" or "-050" to the part numbers for 0.25mm or 0.50mm oversized parts, then have your cylinder bored to fit the new piston.
