Here is what I posted when you asked in another thread :
"Hi guys , found a thread from 2008 that mentions "have been looking through Capt Daybells book on insignia of the RE" .
Perhaps a PM to the poster (Deejayuu) may be helpful.

The post also refere to "the booklet" , so perhaps not a 'full' book ?
