The Waterman 513 NM was introduced, as an upgrade to the 513, in 1952. The 'NM' signified, quite unimaginatively, 'New Model'. It was discontinued after only a short time, when it was replaced by the W3.
At 13.2 cm. capped and an impressive 15.6 cm. in length, when posted for use, it is a good sized and well balanced pen. It features the Waterman box lever filling system, reserved for the higher end pens and dropped for it's successor, the W3. The arrangement uses a metal frame to hold the filler lever, this gives it a more solid anchorage and prevents swelling around the lever slot.
The colour scheme is a range of pink shades in an irregular striated pattern. It has an excellent surface and is an unusual and extremely striking finish. the manufacturing process is such that no two pens are identical, each has its own unique' fingerprint'. The gold filling to the clip and cap band is first class.
The pen has been restored and tested. The filling system works well and the 14Ct. Gold nib writes with a smooth, medium to broad line.
The Waterman box is in fair condition and is probably original to the pen. It came to me with the pen, is from the correct time period so should be kept with the pen.
The Waterman 513 NM is a high quality, attractive and practical vintage pen. Due to the relatively short production run, the NM is not easy to find, particularly in this colour. This example clearly is of collectable quality but would also make an excellent daily writer.
