My understanding is the AMT KW Challenge mixer mold was destroyed as was the W900's molds. The W900 mold was retooled to make the incorrect T600. The crusieliner was reissued about 5 yr ago. As for me I would like to see some new trucks and trailers about a Mack Granite or modern lowboy? I suggested to Stevens at the NNL east show that some newer trucks models would most likely be a hit. To keep cost down I suggested that maybe a guilder style kit that the modeler could then finish any way they wanted.
