Streamlined Pens - 1930-1932 - Beginning in 1930 Carter's began streamlining their pens. They have black ends and are slightly tapered. The sizes go from the small purse pens up to the oversize pens with the #7 pens. These pens do not have the model number on the base of the pen like the flat top pens. These models are harder to find than the earlier flat top pens.
