marine head

[Sooner]

Am removing the complete marine head on Sooner (Cape Dory 27), tank - stool - thru hull - etc  and going back with the vented compost type head that James Baldwin (Atom Voyager) put on his trimaran.  I have searched for some while and can't find that white fan shroud attachment to use with the lewmar hatch vent. As spotted on you-tube - actual name/manufacturer will sure help.
                                        Thanks
