Maybe, trying to compare apples and oranges...but, wondering what the primary differences between an "MTH Scale King Diesel" and a Premier diesel of virtually the same model?? Each seems to have PS3. The price is considerably more for the Premier diesel...that I am pretty sure has the same guts as the Scale King.
For example comparing MTH 30-20649-1 an Atlantic Coast Line GP7 in the "Scale King" line vs MTH 20-20550 a Seaboard Airline GP9 in the Premier Line.
Is the big discriminator the smoke unit in the Premier diesel...that is not in the Scale King diesel?
How about the fuel tanks...are the fuel tanks on the Premier model...beefed up...larger...close to scale-sized?
Thanks for your thoughtful comments.
In the case of the GP 7/9,
the Scale King has molded grab irons, non operating marker lights (only headlights operate) and no see through grills and fans, molded in wipers, no separate lift ring detail on the roof just like premier ps1 models!
The Premier will have operating marker lights, see through fans/ grills, and separate grab irons and cab window wipers and lift ring detail on the roof.
For SD units the ScaleKing will have undersized (and/or squat) fuel tanks, non operating marker lights, no see through grills/ fans, and molded in wipers, lift rings, and grab rails.
On Premier models you have full scale fuel tanks, operating marker/class lights, see through fans and grills, and separate detail add ons like cab wipers, lift rings and grab rails.
