One thing that I have learned on the subject of pre-war sporters by any maker or engraver is that there are few if any hard and fast rules. I have observed and cannot remember an exception, not to say there aren't any, is that the engraving attributed to Kornbrath in a format similiar to this was rarely signed. Again, I cannot remember an example. Conversely if it included one of his game scenes, THE moose, or my favorite (and rare) the cowboys and cactus they have been signed. I cannot remember an exception to this either. Kornbrath did outsource and supervise engraver as well. I think the rifle build period is a critical predictor here. Enjoy some warm weather Steve.
