Welcome to the forum @qvbrun
Are you looking for technical & history reference or model detailing references?
History, technical and some modeling these Jentz books are excellent.
Model building focused these two are outstanding.
If I could only have one book for model building Tiger’s, Achtung #6 Tiger would be my choice and I have a lot of Tiger 1 books.
This thread various-armor-books-for-sale has Achtung #6 for sale at a fair price. I’ve bought several books from seller, he’s A+.
