Is this original 515b cone?

Hi the person I am interested in buying from does not know if it is reconed or not, as as owned it for 15 years, and bought it from someone who owned it 15 years before that, and he does not know if that person had reconed it.

So when you say it was the last repair reference, it means it was repaired by Altec the company itself years ago?
