How old is my Old Timer?

[Billabong01]

Hello All, I recently picked up this beautiful 8OT.
Would anyone please be able to tell me when my Old Timer was made?
There are no markings on the reverse side of the main blade.
Thankyou in advance.

Post Walden tang….probably 1980’s to 2005 when they closed the doors in U.S.A.
I have one that has a stainless clip and Spey blade and a carbon steel long sheeps’ foot…probably at the end when they were trying to use up parts from inventory….nice 8OT btw-good patina

I believe that tang stamp is earlier, probably mid 1970s. By the late 1970s the N.Y. was gone and just SCHRADE U.S.A. was left.

Thankyou all for the help.
I've done a bit of looking on the net and I found this was a date timeframe of 1973-77.
Since the pics, she's had a quick slide on the diamonds to bring the factory edge up to hair popping sharp.
I also found a little leather belt sheath for carriage, and now she's good to go.
Patina will get better with use.
