Here are three that are worth looking at that were sold on public web sites in the past. The 1st is an early 50's 4-6 pinned stag double hilt (Steve Peters SJJP Knives E-Bay Store):

The 2nd is one of the 1st model 4's ever made: A summer of 1945 "two pinned" stag 7 inch skinner (Offered by Nordic knives Solvang, Ca.):

The 3rd and last is a circa 1949 fingergrooved leather handled 4-7 (Sold by Angelo Solino on Collectibleskingdomcastle about 7 years ago):
