@silveringots you once told me that this would be my resource to learn about all things shiny ingot and I must say you were correct. The styles and makers are foreign to me, but it is interesting to learn about them. As you said it would be interesting to document where the stamping was and if you could isolate a time frame. Perhaps, they changed their head of production several times and this lead to changes in stamping. Wonder if there would be any one from the company or a family member that may have notes about it. Thanks for sharing and would make for a great coffee table book!!
