Original String Guages/Brand

[soulwine]

I bought a Lowden S32 12-String #8912 Koa. I am interested to know the original gauges/brand of string used in building this amazing instrument.

What strings would you recommend for this instrument today-gauges/brands?

Could using a heavier/lighter string cause any intonation or other problems?

Thank you for building such amazing instruments. The joy of playing this guitar is unspeakable.
