They do. However the patent says the bloom is "medium sized". I would have thought 1" (quoted in the 2012 reference) was a small rose. Possibly the rose pictured is not 'Mabelle Stearns'. More references might be needed.
Later - after adding more references, it seems the bloom is quoted separately as 1" and 2-3". We've changed the bloom size to the middle 2". The only illustration I can find is in the 1971 reference and is a watercolour by Allianora Rosse. It seems to fit the references beautifully, but I hesitate to attach someone else's painting.
