Is this really a Barlow?

I saw this GEC 78 drop on the Bay. I bought it because it had three words that triggered the buy reflex - Barlow, Bullet, and Sawcut. I don't know about you but that's a trifecta for me.

I have a 15 in sepia sawcut that is a grail for me but damn I'm still trying to get the 15 in sawcut richlite.
