Schrade 7-OT 75th Anniversary - question about the sheath

[BrianB43]

Yep, it's my first time posting a new thread. Please forgive any missteps.

I bought this knife in 2013 on that auction site. There was no box with it but there is no evidence the knife or sheath was ever carried, used or sharpened. The sheath, however, is nicely oiled. I'd swear I read somewhere that these particular versions came from the factory with the sheath oiled. However, I cannot find anything to back that up. Can anyone help me out?

Thanks, Brian
