Look identical to my 'Recaro' seats, same shape, same badge. They're bog std pre-90 MK2 shape seats, I have swapped bolsters over from std seats into mine, frames are identical to std pre-90 GTI seats also. I'm pretty sure yours have been retrimmed too, bog std MK2 leather didn't have different colour piping AFAIK.
FWIW, I swear blind I saw a vag options catalogue pic somewhere years ago with these shape seats with the very same logo on them. It is also an old saying that all GTI seats were made by Recaro, possibly the early ones were. Alos to add an interesting dimension to this discussion, the backrest angle knobs on my seats both have 'Recaro' written on them, whereas std GTI seats do not.
Is the colour of the rear bench 100% the same? could be fronts are random option from another early model, rear bench trimmed to match. The catalogue I mention above I'm pretty sure was MK1 cabrio, and remember they were made by the coachbuilders Karmann, so different seat trim options might have existed plus special leather retrims etc. I know my seats arn't original fabric, they have been retrimmed in velour!
These are definitely not the MK2 Recaros as we know them here in the UK, the UK MK2 Recaros looked just like the Edition ones you pictured, just with varying fabric trim colours.
2nd & 3rd pic down the backrests don't look like any std VAG seat that I know of, look more like BMW/Vauxhaull Recaro seats! Bases look like scirocco ones to me, however interestingly they have plastic trims down the sides just like OEM Recaros do, plus is that an electric switch I spy there?
