Hey Rob,
Like I said, maybe they were bigger due to fruit thinning. Or, come to think of it, I also have a compost pile sitting nearby the tree so maybe it is getting some extra valuable nutrients:) I don't know... But, I have had hundreds of hadens and kents and my "Bombay" mangoes were larger than those in general. I actually have one of the smallest ones(Bombay) left in my refrigerator. I will try to get a weight for you. I would guess a pound and a half or more. I may even take a pic and post, if I can figure out how. It was tagged as Bombay, had Zill writing on side of pot "Bmby", I believe. I'm not saying that it could not possibly be another variety, but from what I've read seems to point to Bombay. I also tried to cut around the equator with one and separate and it almost worked... Almost no fibers from the seed holding the flesh. I can see how you could twist it apart. Just my experience with this mango.
