Challenging Propeller?

A friend has a 1973 Challenger & the Static RPM is "Marginally Low".

The aircraft has a prop with a 60 inch pitch.

Anyone know if that is the ORIGINAL Pitch?

Anyone have a "60" with a Static @ 2325 or above?

The same prop is used on 180's, Archers & Archer II's as well.

Some of these do have different (LOWER) Static Limits.

The Challenger is included in TC 2A13 but not identified as such.

The 180 ( which it IS) is addressed in Section III & XII .

Determination involves using the aircraft serial number.

A concern is whether it is repitched to a Archer or 180 spec.

Thanks for your input.
