Michael here are some pictures.
Marked 68 x 72 -86

I have no idea what that means. I'll measure
the diameter tomorrow.

It is a work of art and it looks like it is twisted for
200 MPH or more.

I have a Warnke that I run on my Varieze. I like it.  Smooth, and the best all around performance of the three props I've tried.

The Warnke is advertised as Almost Constant Speed..  The blade twists under load, as I understand it.

Fixed pitch props are often marked diameter x pitch. In your case, that's probably a 68" diameter.  The pitch may be comparable to a 72" at takeoff, and 86" while in cruise. If you believe the Warnke advertising.  I'd run that prop unless it has obvious damage..
