Just like all piston twins it's a single with dispersed power.

It's a while since I saw Mixmaster but your comment re the wing stirred the other brain cell.
It was a great STOL performer on both and overall a great and safe "twin" for its time.
Around the mid 70's Cessna changed all of the singles wings to a reflex leading edge, I think it was called camber lift although that might have been referring to the new wing tip.
With the exception of the , C207, C210 and i'm not sure about the C336/7, but I have a recollection it did not as it came too late in the production life cycle.
It made a significant difference to the lift and strip performance.
It's that concavity under and behind the leading edge. It's one way of quickly identifying the year model and whether to add a cuppla hundred metres to the TO/Landing dist.
