It looks like that quite possibly there were two New England Queen badges. The
National one was a rotary. The
A G Mason one was the long shuttle. I sure wish Needlebar still had their image gallery.
ISMACS has a needle list that lists the Mason as a "New England (Queen)" and would use the 20x1 as Jon stated in the link above. As you probably know, a 15x1 can be used if dropped a bit. Joe Miller did a hack by cutting a flat magnet (like fidge advertising magnets) to the correct length and inserted, so could use a 15x1 without too much trouble.
