1911L Medium-fine nib
Wow! What a smooth pen! Write like butter even with the cartridge the pen came in. Once I used that up- I went ahead and filled the converter up with another type of sailor ink and didn’t experience any rattling like another review I read. The pen is VERY handsome and I’m a petite woman - I state this as I have the pen in the large and it still fits well for me posted or unposted. The medium fine nib was a great choice for me as I love to write and draw. I am able to product a VERY fine line when using the nib in reverse. While Japanese mins are known for being more fine- my kaweco sport fine nibs is still more fine to write and draw with compared to the sailor medium fine nib. I hope this helps someone!
