Author : Bruce Robertson

ISBN:0 900435 10 0
This is a great book regarding all marks and types of Lancaster's, highly recommended reference.
It also has many B&W Pictures and a series of half-tone illustrations in 1/144 scale!
(Although sadly the Lancaster High Speed Mail Plane is not one of them! )
