Please help Mango ID 50 + years old

[Honest Abe]

Hello mango experts! Please ID these terrible mangos! I need to know what they are so I never plant one again! No fibers, not sweet at all and taste like turpentine a bit. THANK YOU

I need to know what they are SO I NEVER PLANT ONE AGAIN!
So you planted it over 50 years ago?

[Honest Abe]

Previous owner told me. Or I planted it 20 years before I was born.

In Miami, FL. I figured if I announced the year planted and the area, maybe some Miami mango experts could deduce what cultivar it May be.

Obviously good rootstock. Cut it back and graft some good varieties onto it.

Might be a random seedling tree.
