Discoveries!
Found a few plates in the passenger footwell, which had been over painted, bit of scrubbing and they are an ID plate and a lubricant list. I have removed them for a good clean to put back on. No mean feat with the paint overlay! It feels like I should have already known this however, I discovered a lever under each foot well, gave it a tug - there was a big crack! and I saw daylight and a hole appeared in the bonnet! Air-con 50's style! Full of surprises this project, none of them nasty so far!
