An early robust marrow scoop with crisp clear hallmarks, for London 1739, maker John Jacob. The earlier scoops did tend to be heavier but, due to age, did suffer from rubbed, illegible hallmarks. That is what is so exciting, if one could find marrow scoops exciting, about this example. It has all the features you desire: good age, good gauge, good marks.
