I bet after 9,999 bad sales at the market some creative entrepreneur would start selling rotten fruit to throw at you ; ) 

  Without being able to compare the taste of the fruit, I'd wager that it would be in the family lines of Ronde de Bordeaux.

  The two depictions of fruit have both historically been prevalent on the same RdB tree, and the shape of the leaf is spot on to my tree.  

   Blue

Stem looks very similar to my Iranian Red (UK) . I got it from an Iranian bloke. My figs were red though, I mean really red. Only one ripened properly and the rest dropped. But I was told it will produce more as the tree matures.

Figgysid1, One thing interesting too is that the soil on Hilo is very red, right? Though I'm not sure if you used garden soil or purchased?

Hilo area does, pretty much all of the hamakua coast is red clay soil. But fern forest has none. 6 inches of black silt ,sandy soil, from black lava rocks, washed downhill by the rain and settled here. I use only promix hp/bx, Coco coir fiber, coco coir chips, and perlite for all my figs 25% of each per mix. No figs in ground for now. I got 1,100 figs of 60 varieties known and unknowns in pots sized from 3-45 gal. So 96 figs that I'm not completely sure what they are is not that big a deal In the grand scheme of things. :)

Sid,

On that scale, it looks you own the entire island :)

Sid,
After carefully studying your plant and all the information you provided I am reluctant to say that your plant is a Mission Fig/ Franciscana.
The only thing that is still haunting me is the pinkish hue on the leaf stems. Somewhere in the strain there is a trace of a hybrid but it has been dominated (overpowered) by the domestic Mission Variety.
It's a very delicious and hardy variety.

Thanks, I appreciate you taking the time to try to help me figure out what is.
