Aren't bell curves normal in such mortality samples? In this paper it shows the bell curve in the Netherlands at three different dates: 1900, 1950 and 2000. One can see it shifting to the right as medicine and health care improves. Perhaps in pre-industrial society the curve would peak very early - at age 30 or 35.

When I get a chance I'll take a look at Brunt's Italian Manpower and see if he says anything about this.
