Dear hoosierbanana, HarveyC, greenfig and paully22, brianm and bigbadbill
Thank you for providing me with more info on i258. For the time being those pictures are the only ripe fruits. There is one more on the tree which resembled the photo provided by hoosierbanana.
Although I can live with this plant, whether it is i258 or not, while the mystery thickens, I will need to continue with my search. If anyone here willing to part with some cuttings, I am more than willing to buy. Please pm me.
Safar
