My apologies if this question has been asked and answered already.

I have a VP with a fine nib, I have purchased a larger/mediu nib to try (and because I seem to be drawn to having nib choices!). I've been unable to find a video or a site page describing the proper procedure to remove or install a nib on the VP. I've seen one forum entry that said to pull the nib straight out and another that said you hold the filling mechanism and threaded section in one hand while unscrewing the nib with the other.

Does anyone have experience swapping nibs on a VP, or know of a video or definitive site page describing the process? I've also searched in vain for a scan of the owner's pamphlet that came with the pen. I was lucky to buy mine in mint condition, but neither a box nor pamphlet was included.

Thanks so much for any and all help!
