R-2800-75 questions and information please

So, an interesting thing happened today...
A friend of a friend 'found' an R-2800 in a barn near me.
Based on the plate- it looks to have been built by Ford.
I'll post a few photos a bit later, but for now I'd like to ask a few questions.

What birds generally used the -75 version?
Under the model number another stamp says "75M3", and in the corner of the plate it says "FAA Spec 5E8".
What is that stuff all about?
With no paperwork as yet, what is one of these worth?
Given the above about paperwork- is it able to ever be airworthy?

Any information you can provide would be very helpful.

Later- once I have more information- I'll post about the birds that are in the same barn.
One of them is in crates, and is supposed to be a Jenny!!!

Dave,

I found the following information about the R-2800-75 in Graham White's 2001 book: "R-2800 Pratt & Whitney's Dependable Masterpiece":

It is a "B" Series R-2800
8,042 were built, all by the Ford Motor Company
Takeoff Rating is 2000 hp at 2700 rpm
Used mainly in the Curtiss C-46 Commando, specifically the C-46A, C-46D-10, C-46E, C-46F and C-46G

Thanks for the information Todd.

Once I can get the photos into P-Bucket, I'll get them posted.

I am sorry to have not checked back with photos like I said I would.

Turns out- someone's in a hurry, and the engine is now on eBay---

Maybe when they get to the 'Jenny' they will not be in such a hurry...?
