Older Monteverde Invincia With A #5 Nib

[jabberwock11]

Yesterday I received a new nib for my rose gold Monteverde Invincia, a black 1.1 Monteverde stub. Unfortunately neither of these nibs fit into my Monteverde. After doing some research I discovered that the current models of Monteverde pens are not the same as the models which were available when I purchased my Invincia several years ago. With a little more research I discovered that my current nib has the same dimensions as a #5 nib. This was upsetting for a number of reasons, not the least of which was that I could not use my newly purchased nib in this pen.

 

I have contacted the seller who is willing to take back the nib, but this leaves me with a problem. I very much want to put a stub or italic nib onto this pen. I have looked everywhere I can think of for a #5 nib that comes as a nib only (not attached to a feed section). The only places that seem to have loose #5 nibs are xfountainpens, Mazurka Pens, and Fountain Pen Revolution. Mazurka Pens does not have any stubs or italics. xfountainpens only has oblique broad and oblique broad X2. I have heard good things about Fountain Pen Revolution and have no issues with their prices, but I really don't want to wait for 2+ weeks to receive a new nib. Is there anyone out there who knows of a seller with #5 italic or stub nibs located here in the USA? Any assistance would be appreciated.
