This helmet was damaged very hard. Unfortunately it was impossible gently to come back the helmet at ideally form, because the leather decreased. Also it needs to restitch both piece of leather on the sides, back visor and back side of the sweatband. Now the back visor is another. All stitch find old holes except two new holes on the center of back visor because there leather decreased. And finally approx 20% of new finish. All process took more than 4 months.
