Re: 6 and 7 series water pump on 320 engine

With apologies to those already bored by the trivial question of which style of water pump came first on the 6th Series cars it just dawned on me that the obvious source for an answer would be the Packard Parts List which usually gives the engine number cut off for changes introduced in a model year.
However a search under "Motor water pump assembly" reveals nothing, in fact it only lists one pump part number for the 626/633 cars - #158310 and no illustration to show which style. So there must have been some confusion when a customer ordered a new water pump for his front mounted unit and received a side mounted pump or vice versa.
Production in 1929 was at an all time high, they must have been so busy a few things slipped by.
Enough on this matter?
