I enlarged Ed's Navy pic to life-size, confirmed that the front sight base band was 15mm and got a measurement of 5mm for the sight base height, measured from the band...
That would make it 12.5mm from the bore centerline...Compared to the 12mm LP-08 print dimension...Approximately...
Not very scientific, but there is a dearth of Navy Lugers to measure...
BTW: Both P-08 and LP-08 show a 15mm diameter front sight base band measurement...
The blade height is not terribly important, as I make my blades equal to the rear sight height. In this case, I haven't decided on a rear sight...Micro seems to be OOB...
I'd just like the front sight base height to be similar in profile to the 6" Navy barrel base...
