What is the age of this Ball case? It is marked Ball "Official RR Standard" keystone 10k g.f. #9827789. It currently has a Waltham Crescent Street movement in it, and an extra set of screw marks. I am thinking since it has the shoulders flanking the winding stem it should be for a earlier Ball Movement? But which one... Thanks for any help. | ||

Looks like a nice case Keith. The highest quality later Ball-Model cases which we often find housing 998-Elinvars and Ball-Illinois movements have "shoulders" such as you are showing. I would say very late 20's to mid to late 30's would be the age of your shouldered case. regards, bb | |||
