I guess my copy would be from the first printing but should be the same. It's a good book covering all the Sherman variants and is nice to have in my collection. It does not have any line drawings or go in depth like the "Lion and Lioness" series but I'm not sure if or when Dr. Manasherob might get around to covering some of the oddball conversions (my favorite is the Sherman mounting a Shrike missile).
There's never enough time to do all the nothing you want.
