Piston number 1&2.

Early Red Wing drawings show a piston with just two grooves for the supplied cast iron piston rings. I then noticed that later drawings show a different piston design with the ring grooves repositioned to allow a third groove to take an O ring to prevent excessive oil leaking past the piston and out of the bottom af the cylinder. So I made a second piston to the later design.
