The Wahl-Oxford pen uses a friction fit section with a friction fit nib and feed (in other words the most common of constructions amongst the vintage pens). To replace a nib, you first remoce the section from the barrel with the nib and feed in place. Next you knock out the nib and feed from the section from the back driving the nib and feed forward and out of the section. There are knock-out blocks for sale, and knock out rods too, but you can make your own knock pout block with a drill and a 2x4...just drill the hole straight and through the 2x4 the hole needs to be big enough for the nib and feed to fit through loosely, but small enough for the section to sit on to provide support for the section during the knock-out process. The knock out rod can be a piece of plastic (aluminum rod of narrow enough diameter to abut the back end of the feed is more common). This process is outlined in many pen locations/sites. The replacement of the nib requires 1) finding a Wahl-Oxford nib or satisfactory Eversharp one of the right size. Most of these nibs were #4 in size some were #2 but you can always tell if it is right for your feed if its shank curvature arc mates well with the feed when liad on on the other. Wahl-Oxford feeds are available and they should not cost more than $40.00 max. Generic Eversharp nibs are also available for maybe $25-30 and also period correct. If not actually marked Wahl/Oxford/Eversharp, Warranted nibs can be had for about $20.
Hope this helps.

Thanks for the advice Syd but I'm not certain knock out nibs is the case with Wahl Oxfords fitted with Selectopoint nibs. Although I've not tried to unscrew them the photo here shows these Select-o-points to be threaded
http://www.fountainpennetwork.com/forum/in...t-O-Point\ It's the only photo I've seen of a Selectopoint nib.
Could this mean that a specific section was made for the Selectopoints ??? Were there any other threaded nibs made for the Oxfords?
Tracking down replacement nibs is really difficult
Could an Esterbrook nib be fitted as an alternative to the selectopoints ?
