All About Pocket Knives

This is a nice fixed blade knife with Damascus steel and crown stag that I grabbed up this past weekend.
It has an unusual stamp on the ricasso and I can't find anything about it. The stamp is kinda vertical or stacked as follows:
R
A
B
and there is some space between the A and the B. I'll attach some photos. If you have run into the stamp before or know anything about it, please let me know.
