It's more than likely either a 7.5HP or 10HP. Probably has the 7,500 RPM spindle and more than likely does not have the servo turret (faster tool changer). You can tell if it does have the servo turret because there should be an amplifier for this mounted inside the back cabinet next to the spindle drive.
It probably has a 4th axis pre-wire as well...be sure to check for a black dummy plug inside the sheet metal to your right.
We have the manuals on our site under the Services tab, so feel free to browse and read more about Fadals.
Feel free to let us know if you have any questions...we're actually in the process of rebuilding a '93 VMC15 right now...let us know if you want to trade for a VMC15 that is guaranteed to be in excellent condition.
