Hello there, new here, currently entertaining the delusion of a new layout (or multiple) and was contemplating the purchase of the MM class 141/181 (missed the A class last time around), question for the more well informed would this model be suitable for conversion to 21mm or is it a bit to much of a hassel and better to start from new..... basically everything else will be kitbashed or mangled in someway just nice to have somthing presentable in the early days as if the decision to regauge is to be made best to make it early just wondering if this could provide a stopgap anyway nothing set in stone and any and all input and other good conversion suggestions welcome.
