Its a very trick and storied 2800 in my book.
It is unclear if hood, doors and trunk were converted to aluminum. Its possible but not mentioned. Even if done, I still cant call it a CSL.
It left factory as a 2800cs then evolved on track in period with the go faster bits added as owner desired trying to stay in the front row.
Pics of it racing in '69 at SPA are great, basically a street car on stock rims race rubber, side exhaust and a number: a classic gentlemen's race weekend. Good times I'm sure.
I had a email chat with CCK when they were doing the refreshing, they said they didnt have enough of the original 70-71 'bits' to take it to that period, so they worked with what they had.
I think it needs the proper Alpina MOMO 3 spoke rudder.....just my 2 cents.
Going out to buy a lottery ticket now.....wish me luck ;-)
