Help decoding prop serial number

Well Known Member
I have a Sensenich metal prop. The logbook shows the model number to be: 72FMS19-1-85

I believe that is a 72" diameter prop with an 85" pitch.

What does the FMS19-1 in the middle decode to?

The Vansaircraft website also has this note:

Currently the The Sensenich metal propellers for the O-360 that have part numbers starting with PROP 72FM8S(xx-x) are NOT CERTIFIED, and are considered an EXPERIMENTAL prop.

Does the above note apply to my prop?

Obviously I was not the builder, just the buyer :)
