The 2046w that both Terry and I have has to be factory error, as the 2046W frame does not interchange with the 6466 type, frames are different size.
My black over pink tender is a Frankenstein, as the finish on the cab is factory-done, due to heat-stamped lettering. It may be on a frame that pre-dates the tender, curtsey of a previous owner. Some things we will never know, can only speculate, based on the facts that the item displays.
