This is an excellent example of the famous Watermans Ideal. This is the 52 1/2 V set in Black Hard Rubber. The set was made in the USA around 1925 and is in fantastic condition with a deep imprint and crisp chasing to both Pen and Pencil.
The pens have been fully restored and now work perfectly. The pen is a lever filler and is fitted with an amazing Medium Semi flex nib.
