Hi
Think thats walnut burr, cant tell properly as you cant click on the pictures
it was a optional extra, hence why you don't see them very often
its down to every ones taste really, I don't like the wood really, very old fashioned, maybe grow on me when I'm a pensioner
prefer the R's myself, with no chrome and no wood in mine
the seats are quite easy to restore, plenty of video's on youtube
cheers
Joe
