Yes, what I was getting at earlier is that some modern razor makers use adjustable screws and barrels whereas your razor uses rod (the pin) which is 'peened' over washers and can be tightened on either side of the scales. There is another similar arrangement used by modern volume manufacturers which resembles peened rod but is actually only adjustable from one side. It's more like a nail which is cut to size and peened on one side only.
