I came upon your web site by chance today, and thought maybe I could shed some light on the history of my family company (now sadly gone) and the Waverley Pen - for instance the "1" in "Edinburgh 1" is just an early zip code. (Seecaption under the M&C tin  picture on the "Boxes" page).

Although not a collector of nibs as such, I have a pretty complete collection of our company's nibs, and would be happy to help you with any information I may have...
 

...A very brief outline of the company history:

It started as Nisbet MacNiven, a paper maker, in 1770 at Balerno, just outside Edinburgh. It then developed as a stationery wholesaler, after moving into the middle of Edinburgh in 1788.

The first Camerons appeared on the scene in 1840. John and Donald were brothers and my great great uncles, and the name was changed to MacNiven and Cameron in 1845.

My great grandfather, Duncan (a younger brother) joined in 1850, and he  was the one who invented the basic concept of the Waverley nib (narrow waist  and upturned
point). It was first manufactured for the company by Gillott in 1864, and later by Hinks, Wells.

Some of the nibs were made by Wadsworth and Norton, and by Brueton Fowler.  However, Gillott made the Waverley Pens until the mid 1870s, when they were transferred to Hinks Wells. This may have had something to do with personal relationships.  Alfred Gillott (son of Joseph) had been a close friend of my great-grandfather, and one of my great uncles was actually named after him--Alfred Gillott Cameron.   The change was made after Alfred Gillott retired.

In 1900, MacNiven and Cameron bought a factory in Birmingham and started to manufacture their pens themselves. 

The Birmingham factory was at the Watery Lane site from 1900 to 1964.  Towards the end of that period, the factory was making mainly paper clips, of the barrel spring type, but some nib manufaturing continued to the end.  I remember seeing nibs being made there when I was a boy, in the late 50s/early 60s.  The major customers for the nibs in the last years were in India, where there were large numbers of people who were unable to afford fountain pens or even ballpoints.  However, tariff barriers eventually closed this and other eastern markets.

The Waverley Pen continued, little changed, in production for exactly 100 years, until the Birmingham factory was closed in 1964.

There had been a rather unsuccessful attempt to move into fountain pens in the 1920s, but the company gradually moved more into paper stationery items.

The first Waverley in the family, my great-uncle, was born in 1868, so it is a close thing, but clear that the person was named after the pen and not vice versa! You are quite correct that the name came from Walter Scott's novels, and it is his picture on the boxes.

Remnants of the company survive today, one still making some stationery items (not pens) under the Waverley name, but the family is no longer involved.

We do have a lot of memorabilia, and I would be happy to send you some copies and any other information which may be of interest. Unfortunately this may have to wait for a little while, because I have a very busy business travel schedule over the next few weeks. I get to the US several times a year, but rarely, unfortunately, to the Southwest. The only time I have been in Las Cruces was driving through a very long time ago, around
1970. However, if ever you find yourself in Scotland, we would be delighted to see you here and show you a lot of nibs! With a name like MacDonald, you must have Scottish connections.
