Filoli Bulb Slope Historic Daffodil ID Needed

DaffNet Members
I would appreciate your help identifying one of Filoli’s daffodils shown blooming below in the olive walk (2/28/2009).  It was  growing here in 1976 when Filoli  a property of the National Trust for Historic Preservation located in Woodside, CA. changed hands from private estate ownership. I suspect this might be  an original variety planted around 1918. For more information about this historic landmark visit our website at ( www.filoli.org).  
Thanks!
