Please see the full post with photos and links here: Featured Pen - Pilot Namiki 78G . Following is the text of the post:
The Pilot 78G is an inexpensive utility type pen that contains several wonderful surprises. First of all is the price. I acquired all three of mine from winningpen on eBay for about $12 each, including shipping from Hong Kong. This seller always ships quickly and is very reliable, but there are a number of other reputable eBay and non eBay sellers who carry this pen.
These pens come with aerometric fillers and use bottled fountain pen ink, however the coverter is removable if you prefer to use a cartridge. They come in 4 standard nib sizes: F, M, B and BB. The unique thing with these nib is that the B and BB are both italic nibs rather than the standard round nib. I have not seen the BB nib from the eBay seller I have used but I have seen it elsewhere.
As with most Japanese nibs the F and M are finer than their US counterparts.
