Anti-talk: Don't doubt your "find" but at 295H it can't reliably be blamed on the factory. You're in FL. You guys breathe salt by the second. Any small blemish in the paint - maybe caused by airborne grit, sand etc - can let that salt in and you have the perfect climate for corrosion.
Ever seen the window frames of a beach property and compared the corrosion with ones inland?
We're UK based and have just overhauled an R44 RII. The blades were in perfect condition and could carry on flying if permitted. Never delaminated. Never corroded - and we are just as moist as Florida. If you get my drift! (With a lot less baking sun.)
On the other hand, our machine wasn't used for training or SFH and the blades were washed every few weeks. A lot of Robinson "problems" are caused by pilot/operator abuse.
