OK, discussion on two fronts, re bob's comments about early cars SI-3 not having the paint behind the grill, we discussed this about 4-5 tears back on the old forum. I originally agreed that no black paint behind the grill on early series, as it didnt seem needed given the area is largely obscured by the grill bars and doesn't have the defined line on panel of the base trim of a siv-v, but agreed it had in the "A pillar" drains. After researching at the time and indeed posting the pictures on the old forum, period road test cars in the lighter colours such as white and red clearly showed the black behind the grill area on early cars, chalk that up to rootes being pedantic with their new sports model.
Jay as for your comments re the very late cars, alpines running through to '68 I'm not sure... I'm confident to say all the tigers were done, but they finished production earlier than alpines.
