Plastic (composite) prop - Questions

[SFS]

When we bought the boat, it had a two-bladed plastic prop. While the boat was getting a new bottom job, I had them put on the spare (bronze) prop, which is also two bladed. I will eventually replace the bronze 2-blade with a Campbell Sailor 3 blade, and the 2-blade will become the spare for the boat. So, I have no need for this composite prop.

1) I can't seem to find any identifying marks on the prop. Any ideas on how to identify it?
2) Any ideas on what it's worth? 15 inch diameter, 14 pitch, 1" shaft. Pics below (sorry about the blurry one, I can't figure out how to delete it).

I wanna say it's an Indigo Extendo model prop, but damned if I can find a corroborating picture online.
