That root knot is really interesting. I would pot that up separately and see if it sprouts growth.
@roberthu - the published "life spans" for trees are irrelevant in a bonsai context. Trees have open ended life spans, cell lines will continue to grow for hundreds of years, even for the trees listed as short lived. All the life span tables are based on utility, for use for timber, use as an orchard crop, or for use in a landscape planting, the "life span" tables do not mean the trees die of senescence, in the way humans die of old age. There is no reason that if disease control is good, and accidents are avoided, this tree easily could still be with ABCarve for another 100 years. Trees simply do not die of old age.
