I found one that looks similar on page 65 of Original Mini Cooper and Cooper S.
I'm selling them so if they are correct, it would be nice to add it to the description.
Ah yes.
I was thinking of the one on page 36.
You'll have to ask someone more knowledgable than I whether (what looks like) the Mocal 13 rower was standard issue on Mk2s. I suspect they were but I doubt they'll fetch the same money as the Mk1 ones which go for well over 200 quid when they come up for sale now and then.
