Here is the book on the HR. , again, much thanks from Jan for sending and Martin for writing..

Out in 2017...Yes in Czechoslovakian but the photos are very large, nice glossy pages and the details really show well in it..

It is a gigantic book and recommend it to anyone interested in these rings.. If I understand the book shows that the HR could be made by both methods ,,cast and pressed..
Shows the Schwarz HR as well as the 'Diddens', a Wolff, the Dietrich and right on up to 44 dated rings.. Documents,copies, boxes, nice 'in wear photos',,really a very nice book.

Again I invite member 'Equirhodont' [the author] to participate here and share his thoughts..

another shot,,

It was my pleasure .

I will invite Martin into our discussion and we will see whether he will decide to participate. I am sure that if majority will accept any of the rings for discussion, Martin will be willing to provide us pictures for discussion,

Gaspare & Lartiste,

Tell him that if he wishes to post contact address and pricing for this book, he can do it right here.
