Churchill nibs

[Ranic]

I need a fine nib of a Churchill FP but on the AZ site it doesn't have an option to buy one. They look the same as those for an El Grande. So my question is are they interchangeable?

Also is there really a difference between the cheap pump and the Schmidt pump? Does the Schmidt work better?

Not too sure about the nib, but the Schmidt pump works very well indeed!

I have both kits and the nibs from both screw into each other's nib holder so I think they are probably interchangeable. A call or email to BB at A.S. or Ernie at BTW should confirm this.

edit: The Schmidt pump is better than the stock pump that comes with the kits.
