Sorry. Clicked reply on the first page and it added my comment to the end. The brown suede custom one in the liquid mercury aero on page 1 please! New user error!
Morgan will not supply this leather anymore, too many issues with it, I did ask for it 6 years ago and again last year. It is available elsewhere (Melvyn Rutter for example) but it would be a custom fit.
That is strange that Peter has been told there was issues with that leather; in my experience, it wore very well and actually only looked better with age. Perhaps it is less capable of handling wet weather and stains when it gets wet and is therefore less suitable to an open top vehicle?
There is a long story behind that leather but the short version is that Matt Humphries, who designed the Aeromax, was always on the hunt for interesting leather samples and this was one that he was sent. If I recall correctly, it was actually a furniture leather rather than an automotive one but it was used on Aeromax #94 - so if you ask the factory, I am sure they will be able to confirm the exact supplier and name.
Hope that helps.
