Man! That is neat! Wullie taught me a #2 pencil will clean up that corner considerably. I hope you can save the scales and old iron collars if you restore it. I have one with the same design, but etched in instead of frosted. It is hard to see, yet you can feel it with fingernail. I intend to try a vinegar application and lightly buffing the top of the etch to bring it out.
