Hello Greenman62,
        Thank you for your reply! I did ask 7_heads on ebay about the tree that he is selling. He replied back to me saying that the tree is not grafted. It looks like it is from seedling by the description and other details. If the tree is that small, it will probably take many many years to have some flowers and then fruits. It is pretty challenging to wait that long for me.
Thank You again!
Regards,
