Essco will sell you an information manual. If you want an actual, official
POH with the serial number for your aircraft you have to order one from
Cessna. Then you have to update it with all the STCs for any modifications
that have been made to the plane. That POH is required to stay with the
aircraft.

If you bought an airplane lacking a POH then you bought an airplane that
technically is not airworthy. It may not be covered by your insurance in the
event of an accident.
