Dear Ed,
well, it took me seven years with research to finish that book ... and also it took a long time to find a publisher. Now I'm trying to make my book known, because the publisher is not doing any advertisement. I'm not doing it for business and there is no chance to earn money with it, but it's a hobby and good feeling to have an own book
If someone is interested, I can also sign the books ... (for free of course)
With best wishes from Germany
Michael
