WANTED: Lens Hood For FA 28 - 200mm Lens.

Dug a Pentax FA f3.8 - 5.6 28-200mm IF & AL lens out of the collection with a view to trying it out on the K-1. It has a 72mm bayonet fitting. If anyone has a compatible lens hood that they would like to part with or could point me in an appropriate direction I should be most grateful.
TIA.

Paul.
