Mystery interior

Hi i'm in middle of a restoration and  i'm putting my mk1 Golf back to original as possible apart from the BAM motor up front ;0)

Anyway it is fitted with a leather interior which is black with red piping as i've got hold of an original petrol green interior this is now surplus to requirement so I am therefore looking to sell it.  I am aware it is genuine VAG but can't figure out which model it has come from.

I have previously been told this trim was from a MK2 Golf however, having looked at others the rear bench splits in two at the back but mine doesn't.  The rear bench is solid as you would find in a MK1 golf not the MK2.
Can anyone shed any light on this for me i'm thinking could it possibly be a MK1 interior however I am unaware of any MK1 being produced with this interior? cf_emoticons__BangHead:Cheers Rodger 

split fold is rare in a mk2 golf, but the leather interiors didnt come with coloured piping they would have been solid colour. got any pic?

Sounds like mk1 seats covered with Newton Commercial leather http://www.newtoncomm.co.uk/cars/vw-golf/model-134/seats/3154-products-3154/
