Just keep the thread running and would like to contribute more on the forum. I have no plan to get a round "3" EKI into my collection, because the price is very high to me. I think many collectors may have the same thought "A round "3" EKI, the different is only on the pin setting and the one and only one round "3". It is not worth to get one like this. I can get 3-4 cased examples." At least this is my origianl thought. But I have a chance to see a cased EKI round "3" for sale. Can't resist....it's different and the detail is much sharp and better than most of the other normal EKIs. It came with a very nice early case....as a man, how to resist a beautiful lady came with beautiful dressing.......so here she is in my collection
