Are these stock b16 pr3 pistons?
Aftermarket... unless somewhere on the pistons that isn't shown on your photos above, you see the letters PR3 cast (raised) into the dome.
A guess would be JE or CP... pulling the pan and looking for markings on the pistons from below will likely provide more information.
