Only just seen this Phil,
I agree with David (jimjam66) on the nibs front.
I have used and still do use Bock and visconti, only because I'm asked specifically to supply that nib.
Having an alternative "Baufort" nib does appeal and may give me an alternative the the IPG nibs that are not what they make out to be.
At least we could authenticate the quality of your nibs so may be worth a punt.
