Bath with 3 holes on the side????

[wrecked_24_7]

I have never had to work on a bath that has 3 holes on the side. It has the middle with a spout coming out of it, and either side for the levers, i have never had to work on a bath like this, but already know the bath will have to come away from the wall for me to get to it. Is there a mixer valve underneath etc? or is the "mixer" underneath? I am so unsure about this as the customer wants the taps replacing. The distance between the center of the holes with the lebvers is 20 and a half inches, please any help, i know i sound a div!

normally the levers are just seperate valves which then run in copper or plastic to a spout
