Here is the TK ring hapur made for me in a step by step process on this forum.
However; I resized and reshaped the head myself and this is an after picture. The head, at least IMO was too big, and my understanding is he adjusted the size since then.
Since hapur used the correct process die striking rather then rubber mold casting which was never used as others have suggested his rings are much closer to the originals in size.
Gaspare is far more knowledgeable than I am and perhaps he'll add some information here.
These rings are again IMO a good value for the price.
