Hi Rick: The one NW15 refers to (Mistress) is listed on the website as a 'pot Oriental' This website lists several (at least a dozen) pot Orientals, not just 'Mistress'. All of those listed I recognize as common commercial dwarf Orientals available in the market place on a crop rotational basis. Almost everywhere they are called 'dwarf Orientals'.
I'm not sure how these are dwarfed, whether it involves dwarf trumpets or not. Probably not. In fact, I didn't think NW15 actually meant OT in the post. I kinda assumed NW15 meant dwarf Oriental. But this raises the question we have: Are these really dwarf Oriental Trumpets? Interesting.
