now you have to sever the connection point between the 60 and 30 volt taps and make them two separate windings so you can parallel them...

All resistances between adjacent taps are 0.4 ohm.

Thanks for the effort zeoN_Rider, I had already sourced the schematics and am aware of what these were used for. Appreciated.

I'll read from this that you think it is likely worth a shot. I'm out of time at the moment but will have a look at this later this evening to see. Thanks.

looking at the pics, it the lead-outs are also the same magnet wired used for winding the traffo, then you are in luck....

I drilled a few " holes through the filling.
The core pushed out easily once weakened this way.

The insulating wrapping was left intact and undamaged. I needed it for the re-insulation after I had modded the secondaries.

OK, It looks like I basically have either four 30V windings or two 30-0-30 in series, depending on how you look at it. Should be straight forward to modify the windings and tappings from series to parallel.

you are lucky indeed, no need to mess with the center filling...

you can feed the primary with 12 volts to get your secondary phasing right...

and if i were you, i'd just install individual pigtails no less than 6 inches long so that absolute flexibility is yours...
