The Moon
I had an adolescent interest in ancient religions and had read The White Goddess by Robert Graves. When it came to choosing a symbol for my stamp, I rather liked the idea of a moon instead of a star, or other symbol. Discussing this inevitably leads to talk of whether the moon in my stamp is croissante or decroissante. I still don't know which it is, but although I've not often seen it like that in the sky, I think it looks wrong the other way around.
The letters and size were lifted directly from the Tudor Rose stamp found on the Bressan recorders. 

The Logo
The logo I have been using on all my paperwork since 1992 was an idea of Christophe Deslignes. We had been preparing a lecture for the 1992 Calw Symposium and wanted to give a chronological overview of recorder illustrations in treatises from 1500 to 1640. The joke was that the last image, one hundred and twenty years after the first, looked exactly the same. (It is quite possible that the same woodcuts were used.) In the event, I don't think that anyone understood the humour. For the interested, the illustrations  come from (left to right):  S. Virdung 1511, M. Agricola 1528, S. Ganassi 1535, H. Cardanus 1550, P. Jambe de Fer 1556, A. Virgigliano ca. 1600, M. Praetorius 1619, M. Mersenne 1627 and finally P. Trichet 1631. Needless to say the logo has enjoyed legendary success and spawned countless imitations.
The Recorder, A Basic Workshop Manual
I wrote this book after being asked to give a number of lectures on maintenance and tuning and I felt frustrated that there was nothing in print that students could use to help them with practical problems. I now feel that many of the maintenance things in it are either pretty obvious, or highly subjective, and the pictures look a bit dated. I am still very pleased with the tuning bits however, because I think that it was the first attempt to de-mystify and explain this subject in a rational way, without resorting to the usual 'folklore'. The great problem with this book lies with it's publishers, who despite endless promises, have left it out of print for over 5 years. I hope that my experience building this page will enable me, given some spare time, to publish a rogue copy on the Internet.
