I know what it is like to try to make contact with someone with figs, and not get a response. There is a neglected property near me that was a business at some point.. It is overgrown with weeds and has 5 different fig trees. I have knocked and left notes, but no response. No one picks or cares for these trees as far as I have seen. They might be common varieties, but I'd like to talk with the person to find out.
This fig you are showing sounds fantastic, I would like to grow and eat a fig with that flavor profile. I hope you can get permission to take cuttings, but older reclusive people might be hard to reach. I agree though, find some way to make it happen! If they become available, please put me on your list, hopefully I have a good trade you want, or money.
