Sorry to disappoint, Dave, but you won't find the ID of these two manufacturers in my next book!
I have checked all issues of "Die Raeder" available to me (which carry ads. for uniform/insignia manufacturters), but there is nothing to explain who H & F and B & W were.
Perhaps the RZM journals hold the key and I'll have a look.
I've caught the "TN bug" thanks to this thread (and especially Dave's input) and hope to have done justice to what is a fascinating subject in my coverage in Volume 2 of my book with Jack for Roger.
Thanks to all who have been so helpful and generous - with their time, knowledge and wonderful collections.
