Thank you for viewing. This is a Sheaffer fountain pen. The nib is steel. I purchased it as a dead stock item about 6 or 7 years ago, but the manufacturing date is unknown. Made in Australia. I bought it when I was looking for a broad nib, and although there is no width marking, I remember a (B) width sticker was attached. I have included photos that may be helpful in determining the nib width, so please take a look. (The last photo. In this photo, the thinnest line at the bottom is a Parker XF line, and the rest are lines written with this pen. What looks like a black line is a 0.5mm mechanical pencil lead.) I think it's suitable for writing letters and addresses on postcards. After purchasing it, I used it to write the addresses on dozens of New Year's cards, but I haven't used it in recent years, and it has been in storage. The nib and converter have been washed after being soaked in water, but I haven't been able to completely remove the remaining ink (especially in the converter), so please keep that in mind (I was using Pelikan blue ink). If you look closely and change the angle and lighting, you can see small scratches and scuffs from use and storage. Also, there is a line on the cap, but it looks more like a paint line that was attached for some reason, rather than a scratch (please check the 2nd and 3rd photos). There is no box or case. - Color: Burgundy - Material: Resin I hope you will consider purchasing this item, understanding that it is in the condition described above.
