Do Wyvern Nibs Differ In Thickness?

[chunya]

I have two identical Wyverns (101), although the nibs are different. I noticed that on one the nib and feed were not fully pushed into the section so I knocked them out, gave them a clean, as well as the inside of the section, pushed them back in, but they still went no further than before.

I am pretty sure that the nib that won't fit is a replacement possibly from a Wyvern Deluxe (it has the Leicester Dragon) , but although the nibs are different to me the dimensions look identical, and the feeds are identical, so what is stopping them being pushed in all the way? Could the thickness of the nib vary?

I cannot say with 100% certainty, but I believe that Wyvern did not manufacture their own nibs. Their main source was Curzon / Summit, but it is quite probably that they used other suppliers on occasion.

 

Coupled with this IIRC the 101 model was their first & flagship post-WW2 model. If so it may well be the case that they used whatever stock they had, or had access to.

 

There are very few Wyvern experts about, but someone might be able to throw more light onto this.

Thanks for that Northlodge, and I hadn't realised that they didn't make their own nibs.

The pen had obviously been used quite extensively with the nib and feed as it is, but my concern is that if too little of the nib is secured between the section and feed then it may be more prone to bending and therefore damage.

It could just be a photographic illusion, but one of the sections looks to be smaller than the other one? (the lower one, in the bottom two pictures)

Hi,

Just an illusion (to quote Imagination)

Good news is that the problem is now sorted. I again removed the nib and feed and gently rubbed the feed section with some micro mesh, and after a couple of retries the nib and feed fitted perfectly. Put the section through the ultrasonic cleaner to get rid of any debris, and it now is as it should be.

Started a new thread in GB pens with photo and an additional question for the experts.

Most pen maufacturers didn't make their own nibs. The exceptions I know of being Lang's, Valentine/ Parker and Conway Stewart (post war). Like the tin ware, it was a specialist product normally bought in.
