John Montroll from an (old) 10 note

At the British Origami Society conference this Spring, I noticed Robert Lang fiddling around with a UK 5 note. I asked him what he thought of UK money for bill folding and he said that it was 'kinda expensive'. I agreed, and then showed him a simple model with a UK 10 note. I had always known the model as 'John MacEnroe', the tennis player. However, he took one look at it and said 'That's John Montroll!'

So it seems ironic that, on recently releasing a book on US bill folding, that Montroll himself can be folded from a UK bill! I'm not sure if Montroll himself has since been shown this, but if I were a cross between royalty and Charles Dickens, I'd be happy.

Here are the diagrams...
