I suspect that when the mid 80`s +8 I came to own had been restored to close to concours condition circa Y2K that the wheels had been clear coat lacquered, which perhaps 15 or so years later the edges of the lacquer in places was beginning to lift, thus I bit the bullet and put them in to a company specialising in refinishing wheels to have them tidied up.... I suspcct they may well have blasted them with some sort of medium to remove the lacquer. I suspect they may have been powder coated but may just have been paint.. neither of which mattered not a jot to me..Shrug.

Just went out to the garage and grabbed a pic to provide you with an idea of the finish on mine. Looking at the finish on yours I suspect mine would have been similar originally, and to that extent I suspect their current smoother finish suggests mine were perhaps powder coated.... I think yours as they are would perhaps give a good grip/key for the powder coating process...?

Good luck in your choices.
