pistons

Picked up these pistons in a bulk lot of pistons and cylinders from an old dealer, ive been unable to identity them?
Maybe air compressor?

McCulloch had some pistons like that in one of their very early saws. I remember seeing them in one of the IPLs.

You may be right, in the lot i bought there were other Mac pistons.
Any idea of the model?
