thats because private purchase rings are die pressed. I own a few period working dies. Have seen many others..
IF the HR was cast why does the big 'die flaw' remain on the Sig runen? Why wouldn't it be quickly repaired in the next batch of cast rings... We are missing something all of us.
Evidence is not questionable in this case. And it is very clear they were cast. Nor pressed, nor die struck. Cast. The only very detailed and sharp areas are those hand finished, and almost each ring (especially '30 style) has some. We shouldn't complicate what is clear and no need, IMO, strange combos of production processes.
No one will ever answer your question, but you can do the same question for tens of ugly pieces made during the Reich. For example the Bandenkampfabzeichen, one of the most rare badge is for sure the worst ever made.
Furthermore many rings show hand made details that are not what we would expect to see in a such kind of ring (see picture below for example). But our feelings are only "our", and I'm quite sure that nobody during the Reich noticed about the flaws we are talking about here. Gahr did thousands rings every year, it means in the months prior to delivery dates they made tens each day.
