Tree Brand Classic Shadow Stockman

[black mamba]

I have an interesting Tree Brand Classic shadow pattern 6066 ZP stockman that I can't seem to find any info on. I found a 6066 ZP II for sale on another forum, but it has a shield. Mine is an earlier version, without a shield. The box it came in has the silver lid with Tree Brand Classics embossed, and the model number printed on the end. I would love to know when this knife was made, or any other info on it.
Thank you!

Beautiful knife. Never seen a 6066 with scales like that. As always it's hard to date Boker's. I can't read the tang stamp but I assume this one says "Boker Solingen Germany Stainless"? And just from looking at the blade etch and comparing to similar ones my guess is around early-to-mid 1980s-early 90s.

Yes, that's the tang stamp all right. Thanks for the info.
