I just received a MB 149 platinum body with no nib and feeder since I already had those two items. The collar was already inserted. The feed goes in until it hits the bottom and the horizontal notch on the nib is just above the barrel. The nib goes in very quickly and when it hits the bottom of the collar, the feeder is the same if not little longer that the nib.
I have 4 other MBs and changed nib/feeder with the MB platinum resulting in the same situation: the nib/feeder is too loose for the platinum collar.
Do I need to get a different nib or a feeder (I have plastic feeder similar to the pictures of Platinum on websites)?
do I need to get a different feeder? if so will it fit into the Platinum?
Thank you for considering my questions.
