Perhaps the next try will see Lionel contracting with Weaver who is alrady the largest decorator of Lionel cars in the United States.
I don't think Weaver works directly with Lionel but through third parties such as LCCA.
That would be the smart move but Weaver probably would tell Lionel to take a long hike on a short dock during price negotiations.
There is also RGS, I wonder who does their assembly / painting and is it done in the USA. They have some terrific looking rolling stock.
