Nice seat! Would love to find a pair of those for my mk1.
I think they could be South African maybe SA cooper? I know they sourced trim locally and some were like buckets. I'm sure someone will know more!
I see similarities, but I also see differences; especially, in the seat pad (the "sit on it part") shape. I guess, like the wrong colour for a S.A. seat, those differences could be explained by the seat having been recovered and slightly modified in the process.
They look brilliant - would be perfect in my Tartan red mk1!
You can see some differences to the SA seat in the base cushion where it meets the side panels towards the front and the bit where the back of your knees would be.
It almost looks like they could be normal mk1 seats that someone has modified perhaps? Maybe it's just me but the red vinyl of the side panels looks to be a slightly different colour to the rest of the seat.
