Having read your excellent book Peter on the 3 wheeler, I don't think it was 'Sir' Charles that went over to see Pete Larsen's Liberty Ace
Wasn't it Steve Morris and Tim Whitworth ?
From what I remember reading Charles was very resistant to developing the 3 wheeler and had to be persuaded by having it shipped over to Malvern
All the rest is accurate
That's right, and even then he didn't drive it for several weeks. And then, of course, he became rather too enthusiastic...
