There is not a lot of detailed information on the figs in the USDA collection. For example, if you click on the link for Kop Fiomi it will take you to the page where you will find most of the available details. This page describes where the fig was collected and who donated it to the collection. The "observations" link contains some descriptor information. For our general interest, the information appears to be minimal.
It is unfortunate that there is not a photograph of the fig (inside and outside) and of the leaves. Also missing is a general description of the taste.
The three figs that you mentioned are currently on the "unavailable list," meaning they cannot not be ordered at this time. Only a portion of their collection is available for ordering scion.
Eventually, I assume some of these figs will become available to the public. Then they will get tested and photographed, and comments will be posted to one of the forums.
I hope this helps. Perhaps others will have other bits of information to add.
