Nibral props

And I bought a set of 2 blade Federal Equipoise NiBrAl 17D x 19P x 1.25B props in great ISO 1 scanned-spec condition for $400. New , each prop would go for well over that I believe.
Have you had them scanned and serviced since last used? It makes a difference.

Here's the only reference I could find for props on Chris Crafts with those numbers:

Your measured radius of 8" would indicate present diameter of 16" and the 18P noted in that Chris Craft post suggests 18" nominal pitch ( cupping affects effective pitch). So, they ...may... be: 16D x 18P x 1.25 Bore / with cup, but you should confirm that before advertising for sale.
Here's a link to advice on calculating pitch of a prop.
http://propellerhub.com/simple-pitch-measuring.html A quick search will turn up many more such links , though my anti-virus warned me not to open one other due to definite malware on the site.
You can also take them to a PropScan shop for a free scan which will confirm D x P x B , cupping, and condition of each blade and average as an ISO spec.., and whether they are a closely matched set now.

Unless you originally bought them new (apparently not) and kept them carefully boxed, your not using them doesn't mean they are unused, & so would have indeterminate present spec.. If they prove to be in very good shape, that $375 asking price would be a good fair start, IMO. But like everything else, they are only worth what someone will pay for them.
