The copy I have is "The Ailments and Diseases of the Racing Pigeon and How to Treat Them." The copy was updated in 1993 but as you say things get banned etc etc.
Thanks for all of your replies. Yes it's used for treating canker and I read about it in an 'Old Hand' book. Doesn't look very promising judging by your replies. Rembrandt2coo - don't understand - sorry!
