Last night I thought I'd be smart and get the information from La Lancia (3rd Edition) .... but while that's pretty good and lists facelifts and series for the models there's nothing for the Delta other than 1600 HF Turbo and then 1600ie HF Turbo.
Our database ( wot I setup with Andy Collins ) lists models like this :
Delta 1100
Delta 1300 (4)
Delta 1300 Cabriolet (1)
Delta 1300 LX (6)
Delta 1500 (7)
Delta 1500 LX (1)
Delta 1600 GT (2)
Delta 1600 HF Turbo (6)
Delta 1600ie GT (3)
Delta 1600ie GT (FL) (1)
Delta 1600ie HF Turbo (14)
Delta 1600ie HF Turbo (FL) (12)
Delta 1900 TDS
The number is brackets are the known cars of the model type. I suspect the FL are the post 91 cars which should have the parts described - ( so these probably need re-classifying
)
@Simon : I remember the conversation about that one but didn't get to see it in the metal.
