This is the nib taken with my mother's day present.
That is interesting. The opposite was noted by an Amazon buyer.
On the Amazon Bulow X49 Crown
review, a buyer notes 'One point of interest, the pen is sold as Bulow, but the nib is engraved with the brand name "Jinhao". Not that that fact bothers me, it is my understanding those are also pretty good pens. It's not the same style nib as in the picture. The one I got has a classic pattern nib.'
Apparently sometimes the nibs are engraved "Bulow" and sometimes they are engraved "Jinhao"-- they are probably both German nibs, is that correct? I wonder if they are the same nib, but they ran out of the "Jinhao" stamped ones and used the manufacturers name?
If one googles "jinhao fountain pen", one of the advertising links at the top is "Amazon.com Buy jinhao fountain pens at Amazon! Qualified orders over $25 ship free". If you click on it, a list of Bulow
fountain pens appears. The model numbers match the Jinhao "X###" models.
