The Mentmore Auto-flow was introduced both as a lever and button filler versions in 1935. The first version, this pen, had a ball end clip, later replaced by the straight clip.
This pen is an excellent example, it has been fully restored, including a new ink sac , and is in first class working condition. The filling system is quick and convenient, filling with just one press of the button. The 14 Ct. Gold nib writes with a smooth, firm fine line.
The cap is a screw fit, the threads are set high inside the cap so it is pushed into place before tightening.
Solidly constructed in celluloid, it has a very striking mottled pearl pink finish with an excellent surface and crisp imprint.
At an impressive 16cm. in length when posted and with a proportionate width, the Auto-flow is a large pen with a good deal of presence and a high quality feel. It is, at least, on a par with the better known English pens of the period, and is very collectable.
