Hello FPN family. I am a younger collector and calligraphy enthusiast and I happen to stumble upon a book of pen nibs from my home town and thought it would be amazing if I could complete the collection of these old nibs. Now it's not like they are super well know like Esterbrook or speed ball. However I was wondering if any persons here would be able to help in and way possible, even be able to tell me if my search will be fruitless or if sifting threw hordes of nibs at estate sales is the only way to go? I'm attaching a photo of the booklet and the 4 nibs I have so far. If any other info is needed, just let me know. I am really excited to see if I can complete this set.
