James ;
Very good .
I open Laine almost everyday
Not only helmets , but as know
I collect shoulder straps and some epaulettes
so quick reference for the cyphers and underlay color
only problem it is pre war so does not cover
the late cyphers and the late cypher changes .
Mike Kelso's book will cover all that .
Due out ( I hope ) Jan. 2017
Jim's books are also good
I have some of them
I know a lot of the members are not fans of or
collect miters
but I am and I do
Jim did a really good book on just miters .
