Sorry I don't. Don't see it with a cursory search in google scholar either.

Oh well. I'll still mention this in Immortality: A Practical Guide if that's okay with you.

Oh if you want to cite it I'll look a little harder.

This review actually seems pretty thorough and reports a negative result (though still positive for people who have already experienced a CHD event): http://circ.ahajournals.org/content/103/1/52.full

They discuss why they think positive results happened in previous studies. I'm updating away from the hypothesis as a result of finding this. Blood donation still has enough other studies showing various benefits and essentially no studies showing harm (except for excessive donation, more than twice a year IIRC) that I think it is worth it, but the mortality effects might not be very high.

Keep in that one of blood donation's supposed mechanisms is to prevent iron overload, but only ~0.5% of the population has iron overload to begin with. See ChrisT's comment.
