Are there any stamps or markings on the trem block? Its going to rather hard to distinguish honestly because everyone and their brother made Licensed Floyds.
I can say that it doesn't appear to be a Gotoh or Ping because their logo is stamped into the baseplate up top where you can see it.
Its either aftermarket or OEM equipment from a production guitar.
The shape of the baseplate at the rear certainly has a distinguishable feature by being angled back toward the finetuners, that's what sticks out the most to me.
Perhaps someone has a similar one and they can shed more light on this shot in the dark.
