Waterman's Numbering System
Waterman's Numbering System
About 1898 Waterman's began using a standard numbering system to describe its pens. This system was modified slightly in 1917 and lasted until the 1930's with exceptions creeping in after 1927. These numbers were stamped on the end of the pen as follows:

Example
Example
A #0552 1/2 is a thin, gold-filled lever-filler with a No. 2 sized nib. A #404 is a silver straight cap with a No. 4 sized nib. A #58 is a lever-filler with a No. 8 sized nib. About 1928, Waterman's began making pens that did not use the above system, such as the #7's, #5's, #94's, #92's, and #32's.
