Hope this is in the right forum...I have heard that Johnson stamped a "W" on his waxed sheaths that he made for the model #16, supposedly this was done staring in the early 1970s

I have a model #16 black micarta handle, brass lined thong hole with no "W" on the waxed sheath (the sheath is identicle to a Brown Micarta unlined thong hole version vietnam era #16 knife and Johnson waxed sheath that I also have)

My question is the lined thong hole would date the knife to later 70s at the earliest, right and I know that the knife and sheath have been a pair since new so what gives?

"Is this just first in last out" or am I missing something...Thanks in advance for any help I may recieve here.

By the way Rocky that is quite the nice Tennite!
