Ok... according to the prints the top of the front sight base on a standard P.08 is 10mm from the bore centerline. On the artillery model print, the distance is 10.4mm plus 1.6mm or 12mm. That 2mm difference is 0.0787402 inches.

I would recommend you go with 2.5 to 3mm higher than the standard and then determine your requirements by using temporary front sights (a headless stud filed flat on top inserted into a threaded hole in the front sight base that will be covered by the sight dovetail) to experiment and find the point of impact. Once you know the ballpark for the front sight height, it will be a lot easier to extrapolate the correct base height for your custom barrel...
