I believe the Mini headlining material pattern changed in the early 1970's but I'm trying to confirm this and identify the change point (car number and/or date). The first two pictures below are from my unmolested 1970 MK II Cooper S. Apparently this pattern continued into the early Clubmans but may have changed to the type shown in the last image around 1972 or 1973. The Mini parts books and trim guide show the same part number for the headlining throughout this period (HYA2173) but the material type specified changes from #407 Grey to #488 Grey.
There's been a couple of discussions on here in the past but, from what I can see, they concentrate on the 1960's cars, not Clubmans.
If you have a 1971 round-nose (Cooper S, Mini K, etc.) or a Clubman of any vintage
with original headlining could you please compare it to the patterns shown and report back with what you find. Please include the car's delivery date as shown on the ADR compliance plate.
P.S. If you have another grain pattern altogether please post a picture of it.
P.P.S. The Clubman GT doesn't appear to be any different from the other Clubman models, but please advise if you know otherwise.
