does any of you have the book "Die Rechenschieber von Nestler in ihrem internationalen Umfeld", by Guus Craenen? Published in 2001 and the first book about the Nestler silde rules.
Ideally, I would like to buy it, but I'm also happy to take a look at it.
I found a reference copy in a Hamburg library. However, it will still take a while before I come back to Hamburg.
