This is what I've managed to trace from an onboard EL-inverter circuitry.

The problem is that the transformer (T) was broken (only the legs were in place) and the device itself has been a measuring equipment of some sort, not much bigger than a typical remote controller so there has not been much space for the transformer. The device itself was running from a 9V battery.

Could anyone suggest what kind of a replacement transformer I should be looking for it?

Can't help you with that, but i do know you can buy cheap mini-inverters similar to that thing to drive EL-sheet.
They are little squared black boxes with 4 pins.

But it would mean extra parts hanging from the display with everything else already built-in.

There's no IC. The inverter-parts are with the rest of the control electronics.
