Gary...this is the front and back of that 76 125 piston we spoke about yesterday. The only markings are a directional arrow and 020 engraved on the top. Because of our conversation and the slot in the intake side, I'm assuming it's a KTM piston and not a Sach piston. True?

Yes that would be correct.
The slot is for the booster ports the KTM cylinders have. Someone driled the little holes in the ffront to be sure the exhaust bridge was extra lubricated so as not to drag seize in that spot. THose are bigger than most you see however.
