Gotoh is one of the first to make copies of the Floyd Rose, and they have gotten very good at it.
Gotoh, Aria, and Fernandes had a long relationship together, and Gotoh were heavily involved in the FRT-10/11 tremolo for Fernandes starting in the mid-1990s. That being said, they could have fabricated tremolos for Fernandes earlier than that, but we currently don’t have evidence.
