Before they go up on eBay, I have a set of wingtips for a '59 model. No corrosion, treated with ACF-50. Red jet-glow finish.
Also have set of wingtips off my 1965E model. Includes the nav lights. Fiberglass.
PM me if interested.

Just to add a bit - the '59 wingtips above are metal, not plastic or fibreglass.
In short, they're very durable. I put a set on my '64 D-model. Very nice, and hard-to-find. The best part is they'll fit every 150 and 152!
They use standard Grimes "teardrop" nav lights, whereas Cessna typically uses a modified Grimes base and fairing, so you may have to change out your nav lights. But, in my opinion, it's worth it.
