Sorry I am so late to the party Guys!
I have given this a lot of thought, & here is my
opinion.
Matt's knife is a Camillus made knife. (I have a Grand Daddy Barlow Buck bolster in my bolster drawer !). :thumbup:
It is more than likely the original approval sample made for SMKW to use as a photo sample. This Buck knife was made
after the Remington Musket Knife. When Wally Rockwell (Camillus Sample Maker

) was charged with making this knife, rather that having to make a blade from scratch, his options on available blades would have been limited. It was not a frequently made pattern. He took a left over Remington blade, sanded off the Remington Tang stamp, annealed the tang & stamped Buck on the blade.
To confirm this, if you measure the thickness of the blade at the stamped area of the tang, it should be .010 - .015 thinner than the production version. :thumbup:
I believe Tom was confused by the "Prototype" engraved on the pile side of the blade.
Definitely
NOT done at the Camillus Factory! :thumbdn:
Unfortunately,
IMHO, the seller (James Parker) tried to
prove it was a prototype by engraving it!
He did not realize that the Musket 1 pile side stamp is fair proof of it's prototype status. :thumbdn:
I assume the knife did not come with the box & papers?
This too is correct! :thumbup:
The boxes & papers would have been made during the production run, well after Wally made this knife.
I hope this helps.
Please remember, this is an
OPINION, not a statement of fact!
