The sheath to me just doesn't look like the quality work that Maurice Johnson was recognised for. If this is his, he made it left handed and with one closed.
Take a look at the original picture of this sheath (front side) and the back of the first two sheaths on pg. 3 (I believe) -near exact, save for the chrome snaps. No doubt, it's a very early MJ/RMK sheath.
