Looking at the end of the gutter, and seeing as there is no trim where the vinyl roof ends, I would say not. Also I don't think W&P ever fitted Cosmic arches, but they could have been added later.
It's like what my painter friend Donald said to me
"Stick a fork in their ass and turn them over, they're done"
Cilla Black's Wood & Pickett Mini
"Bobby Willis and Cilla Black’s 30-year romance has been well told and proved a fairytale in the world of showbiz. Eight years after their marriage in 1969, Bobby surprise surprised Cilla with a brand new 1977 Mark IV Mini 1000 that was extensively upgraded by Wood & Pickett on Abbey Road, just a stone’s throw from the recording studios; the spiritual London home of Merseybeat. The upgrades included solid black paintwork, extended wheel arches, Margrave leather interior and walnut dashboard. Recently restored whilst retaining its originality, the car will be going on sale on Valentine’s weekend this year, in the 60th anniversary year of the Mini, at the London Classic Car Show and is estimated to sell for between £30,000-£40,000." https://www.thelondonclassiccarshow.co. ... -car-show/
