I apologize for the photos, but it is the best I could get, the marking has a "Y"shaped indent with tiny initials, and a triangle at the center of the "Y". I think it is marked RLB in the "Y", R in the upper left, L in the upper right and B at the bottom of the "Y" . The next mark is "Sterling", and the last is "Jan. 28, 08". Thank you very much for any information you may be able to provide.
