Bachmann will print purple spots on the box if Paddy Murphy asked them to. If Bachmann have played no part in the production of these models then why is bachmann credited on murphy models website? BTW, as far as I'm aware, murphy models does not have either a factory or manufacturing staff. The debate on the manufacturer relates to the build quality of the locomotive model itself and since it is made by the people who make bachmann models and made in the factory that bachmann models are made in then it is indeed a bachmann loco(I'm not arguing with you over who makes the box!)
Can you show us the box?
