Carter's is best know for a vast line of inks, paste, ink eradicators, and other office products. In 1927 they entered the Fountain Pen market with a line of excellent, well built fountain pens and pencils. These are quality pens and compare favorably with the other pens of the period. Unfortunately for the company the Great Depression radically changed the pen market in the 1930's. In a wise move Carter decided to drop pens and pencils from their product line late in 1931 or early 1932.
The jade green and the black and pearl plastics from this period are not very stable. They tend to fade and change colors over time. It is best to remove the ink sacs from these pens if you have any. Another problem area is the pocket clip. They are held on by a small steel tab that is prone to rusting and the pens are frequently found without the clips. They are a little tricky to change out and it is hard to find suitable replacements. The clips also tend to have considerable brassing.
