There is an article in the Arrow on doing just that. I wrote it several years ago.

Hi all,

I am considering an n&w kitbash effort. Does the group have any advice on where to start if i desired to take a bachmann spectrum heavy mountain and updated it to a 1950 (ish) non-streamlined class k....either k2 or k1? I see one major difference in air pumps and feedwater heater.....anything else?
