Need to pull the turbine housing off and measure the inducer and exducer of the turbine wheel. Only way to know for sure what you have.

If it performs the way you want why worry about. It's not like you can change the turbine wheel to something else anyways. Those old dinosaurs were good turbos in their day, But that day has long pasted. It was probably built out of a TV7512 or TV7511. Much like the old Turbonetics Thumper Turbos of Yesteryear. Those TV75's have been obsolete and out of production since the early 90's. Parts where hard to find for them 20 years ago.
A quick Google search finds the TV7512 Turbine Wheel has a Exducer of 84.79 mm, and a Inducer of 96.85 mm, 11 Blades. A TV7511 has a Exducer of 70.9 mm, and a Inducer of 102.3
