To be honest it looks like one of the new fakes, have a look at this thread and looks this picture from that thread. The fake buckle is on the right, compare the lettering to the one you have shown, I will have another good close look later as I dont have much time at the moment
Ben, I guess you're right. Especially letter S.
boy am I glad I don't collect buckles.the letters are not the only difference I can see.
