Bit of a contentious issue what constitutes a Lee Speed and what doesn't. Many consider only the ones stamped Lee Speed Patent to be Lee Speeds where others argue that the ones after the patent expired are still Lee Speeds, the only difference being they were made after the patent expired so don't carry the stamping. Army Navy was only one retailer among many, most British gunmakers of the time offered them and not all were made by BSA. I can see both sides of the argument but there is no argument that those carrying the patent stamps are Lee Speeds. Someone else can argue about the rest.
