I can second that, Alan. Since I wrote the book on the Trusty I have had many calls from people with Trusty machinery- more to add to the Trusty Register so that it builds up into an accurate picture of the surviving machines and their distribution around the World.
Many people don’t realise that these horticultural machines were exported to all parts of the British Commonwealth as well as parts of the World that had seen the worst fighting in the war; the UNRRA was set up after the war to get countries back into food production to feed their populations, and “our” machinery played a large part in this.
What we need is more books about “our” machinery; we all collect information to satisfy our own curiosity, but what happens to it? It may get passed on by word of mouth, but it is far better to put it into writing so that it is there for future generations.
