Montblanc Used By Searle

[MolesworthTwo]

Hi All,

Ronald Searle famously used Montblanc pens to create many of his works in the fities and sixties. Below is a video that shows him drawing, using the back of the nib. Any ideas on what type of pen this is? The ink flow is amazing too. I have searched for a long time but with no luck. I hope that someone here can shed a light on this.

Many thanks!
