It's a Robeson 512224 made by Camilus somewhere between 1965 and 1977. 9" oal 5" closed 4" blade with smooth bone covers, brass liners, nickel silver bolsters not sure of the blade steel but believe it to be carbon.
I have the smaller cousin of that "granddaddy" sized Robeson, a #521179 Barlow, (regular sized; photo a few pages back), same blade profile, same lined bolsters but in Delrin. Earlier non-Camillus Robeson Barlows I've seen had rounded bolsters, so these CC-made versions are rather distinctive compared to those. Nice find!!
Nice! :thumbup: I'm encouraged by the fact that I guessed right about the origin (I was convinced it was Camillus). I have what I believe is a black Delrin version of that same knife, only not even in the same ballpark in terms of condition. I am considering a slight reprofiling of the blade, if not an outright rehandling, but all the telltale signs from your knife are there and would remain.
Now if I could only get a NOS version.![]()
And you were right! I posted a photo of mine on that "other" forum, which has a Robeson thread, and it was identified by Robeson gurus as CC-made after '65, so fits right in with what r redden said above. I guess the older knives are more desirable to some, but I'm jazzed to have a Camillus-made version.
If only any of us could find a NOS version!!
