Car riddle deriddled

A return visit today gave me a view of a servicing manual on the front seat; 1969 Oldsmobile Chassis Service Manual.


And closer inspection shows that Ninety-Eight was one of the models coverered. Well done chaps! This one differs by having an after-market grille.


The full list of models being:

  A????  Vista Cruiser  Cutlass  442   &   Delta 88  Delta 88 Custom  Delta 88 ???  Ninety-Eight  Toronado    

So that just leaves the mystery of the hood ornament...
