Could this be a Patented 1916 Marbles?

[Leo7504]

My wife got me this one for Christmas. Inexamining this knife I noticed it had been aggressively cleaned and buffed. I noticed that opposite the Marbles mark there was some barely legible writing, I thought I could detect an AT. When I compared that to my Patented 1916 model the AT appeared to be in the same location as the Pat 1916. Could this be a Pat 1916 model?? It has the roller coaster stamp and a 3/8 in nut. The 1916 model I have has the smaller Marbles stamp and 1/2 in nut and the small hilt. Could some aggressive grinding removed or obscured the mark? Someone with a good understanding of older Marbles can weigh in. I have Arni’s book and it says early models of the Pat 1916 have the sight mark, and I’m assuming the roller coaster mark after that, if I’m right that would make this a 1923-25 model, albeit aggressively cleaned. It’s hard to reproduce in a picture but if you twirl it in the light you can definitely see the AT.

It might well be a Pat 1916 but there is nothing special about knives so marked. They used that mark into the 1930s and there are plenty of them out there. That poor knife has been used and abused!
