Ah .. I found it.

It's an artifact of the laser engraving process.

Note: What's pictured is in glass & sourced from wiki

however

VERY similar to what I'm observing on blade blank.

Thanks that case is one of my favorite patterns..

Derek .. have you seen these tooling marks before ?

It's like a series of center punches.. sort of. I'm familiar with embossing & have never seen that result in this. It's as if the characters are "written" on/in the metal. e.g. especially evident in the "M" & "N" .. where the change in direction causes the metal to deform into the area previously marked.

.
?? any clue as to the method ??

.

Thanks

Derek, there is not a lot more I can tell you except I do not believe this was something someone has added. Camillus is not a brand I have collected and I know they have been closed for a significant period of time. What I do not know if someone has picked up the right for the brand. I look at knives every day, pre 1970, on eBay and this knife was posted there. I am equally sure this knife is not 1970 or before. This could be something they were considering before closing. I do know that this knife has never been sharpened. I will be showing this to my club associates as well as to some dealers.

Derek,

You are quite welcome. I was happy to oblige!

Cheers, my friend!

Here is the video that Stefan Schmalhaus made for his Taylor's Eye Witness Barlow...

Thanks for friending me! I'm shocked because I thought we already were friends! Goes to show what I know.

About the Taylor's Eye Witness Barlow. It's from their Premier Collection. Here are a few more pics with more info at the bottom... 

That should be enough pics to give you a pretty good idea of what it looks like. It was handmade by Russell White who at the time, about 5 years ago, had been crafting knives for Taylor's Eye Witness for well over a quarter of a century. Of course, TEW are in Sheffield, England. Here is a link for one of Taylor's Eye Witness distributors listing this particular knife: TEW Premier Barlow

Our friend Stefan Schmalhaus did a video of his TEW Barlow with wood scales. I believe aside from mine having Genuine Mother Of Pearl scales and his having some gorgeous wood scales the knives are identical right down to the file worked backspring. I'll post his video in the next frame...
