See https://www.roblight...brochures.html: there is no 1987 'general' brochure on that site but the 1987 Park Lane brochure is there and shows what was fitted (as well as the speakers). The Mayfair would almost certainly have had the same model of radio.
I think the flat speakers as in your photo only come in during the early 1990s. The Park Lane brochure shows two 'pod' speakers which sit on the rear parcel shelf, with the grilles facing into the car. These are what I have in my 1989 Racing, and they are shown in the 1989 Mayfair brochure too. They are rare!
Earlier models (c. 1985) had a single speaker on the rear shelf.
Hi I’m sent to an error page through that link, can you try sending it again because that’ll be ideal help.
That’s good to know that the grills are rare, they where a gift from another mini owner so once replaced I’ll see if he’d like them back or I’ll save them to gift to someone else restoring a 1990s model.
Edit- I’ve found it - https://www.roblight...e-brochure.html
Can’t find a reference or picture in relation to what the speaker grills looked like however
