While we're on the subject of oil pump ID, lets recap:

1. First generation Packard - most common
2. Second generation Packard - different bypass design introduced late and least common.
3. Golden Hawk - same as first Packard, but without vacuum pump.
4. Hudson/Nash - unique pump and pan

Question - has anyone seen a GH or Hash pump with the second generation Packard bypass features?
