Bob: Back in the day, Korea builders had far less technology to draw on and many early models were basically individually hand built. I would venture to say that if you took any 10 locomotives built in the early 80's, you would find several places where construction differed and I'm not talking just detail. I expect the GS4 falls in that category. When I first started working on brass I would carefully dismantle and label each item (including screws!) in bags in an effort to get every piece back in exactly the same position. Otherwise you risked the "hand tweaked" factor.
Later, as builders invested in more sophisticated computer assisted/controlled equipment, everything became much more standardized. Modelers today have things way too easy! <GRIN> Jim Kindraka --- In [email protected], "adguytrains" <robert_ho...@...> wrote: > > Bob... > > Probably most important is determining if the lead truck is centered (front > to back) between the cylinders.
