This is a great little book on World War II Aircraft as per advertized by Amazon. There are about 100 aircraft listed etc.
There are specs for each. This book is divided by Country
Each aircraft has two pages and one photo. As it says on the
front of the book.....A mine of information. This is correct.
I am not an expert but only the common aircraft for each country
are in the book. This is a great book for eight bucks. It is
a pocket book.....since it fits in your pocket! This is good for a first reference. If you need more info there are other books/the Internet/the public Library.
