If this is the same Tiger book as The english text 'Tiger & King Tiger tanks and their variants' by Spielberger then I'd cheeerfully reccomend it as one of the best technical books available, I've felt no urge to buy anymore mechanical data on the mark 6 since paying a rather high price for an admittedly rare copy. The best news is it seems to be due for reprinting soon and is being listed at about half what I paid last year. Still not exactly cheap, but well worth it.
Edit: Amazon.co.uk: Tigers I and II and Their Variants (Spielberger German Armor and Military Vehicle Series): Books: Walter J. Spielberger,Hilary L. Doyle republished in august.

Another classic read well worth hunting down is David Fletcher's 'Tiger! - a British view' which presents contemporary reports from the very first glimpses through to the capture and assessment of a working example (lovely old '131' itself). Mr fletcher does little more than comment in the margins and lets the different soldiers, scientists & intelligence departments of the day speak for themselves without any of the intervening decades of puffed up 'legend' intervening. It also contains a facsimile of the vehicle handbook as produced by the British, that alone makes it worth owning.

Cheers,
Adam.
