Thanks Len,
In the past, I made many efforts with writing about vintage radio design and construction, but found that the main interest in vintage radio these days is restoration. Several years ago I produced a number of radio construction downloads, but they turned out a complete waste of time, so I finally erased them all from my catalogue! There is no possibility of a book, because I will be 80 in a few days, and not in the best of health. I have given up ship model building as well, and all I am good for now is ship plan and profile drawings. These enjoy moderate success, are easy to do, and don’t involve much energy or toxic dust fumes.
