KG 6 & 66 histories

[indianer1]

Dear All,
Any news on the KG 66 history, author Marcel van Heijkop ? Also, any news on the 2nd KG 6 history, reportedly being written by M/s Ab Jansen (sp?) and others ?
Also, am considering a purchase of 'Wir Flogen gen Westen" and would like feedback on the book, esecially the photo coverage of the Ju 188 (in terms of new images) I have read some of the earlier feedback now archived in LWAG.

Thanks in advance,
