Well, there was a similiar thread lately in a German board and I wondered what kind of writing instruments do other Hamilton collectors use. So please feel free to show your nice writing instruments.
It became a second collection hobby for me while still not that big like the watches, but good old vintage fountain pens are something I really enjoy.
An Eversharp Skyline in the grey moire color of 1946. The pen was designed by Henry Dreyfuss, the men who also is responsible for the pretty cool design of the 20th Century Limited train and in this way fitting to be used together with a "watch of Railroad Accuracy".
This time with the train as background:
A Sheaffer Balance in brown with the lifetime warranty (or white dot) from around 1939/40. It is one of the slim pieces. Sheaffer made them in different sizes, Ladies, Jr., Senior and oversized big pens. While brown striated is a very common color it is still a very nice coloration and this one writes really good.
The same pen in its full beauty:
A Sheaffer Balance Jr. from c. 1937/38 in the standard edition. This one is shorter (well its a Junior) with 12 cm (the brown one is about 13.5 cm). The coloration was called carmine red and is somewhat rare.
Why, dearest ... how did you ever guess ... I've been wanting a HAMILTON WATCH!
