Hi Adriano and all others,
No there is not First volume ready yet.
However there exists unofficial Zerstorer Research Workgroup.
There are two guys who works on ZG 1 history...Early years, Russia, and RVT.
We know one man that is interested and works on ZG 26 detailed history.
Two other researchers are working on I. ZG 76 and II./ZG 76 histories separately. The later mentioned will be the first one out, AFAIK.
And me, working on ZG 76 1943-45.
So a lot of data possibly concentrated. But all of it needs more or even "more-er"

time and effort.
I am planning mine to be published hopefully in 2012, if all goes OK. We will see...it got complicated when WASt stopped the replies

But we manage somehow I believe.
regards
