Old Gori Folding Prop - Any Good?

I'm cleaning out the shop and found my Dad's old Gori folding propeller. It still looks good, with only a little bit of surface corrosion here and there.
The problem is that it has a plastic bushing/sleeve that separates the inner part that slips over the shaft from the main outer part of the propeller, and this plastic bit appears fine, but it had deteriorated enough to allow the prop to spin relative to the shaft when under load.

Does this have any value to anyone? As it is now, it is clearly UNSAFE, but I hate to throw away such a magnificent chunk of Bronze. It is FREE if anybody has a use for it.
