Another email this morning (August 15) from Showcase Miniatures includes 8 new N scale semi-tractor cabs from MadAboutCars. https://www.showcaseminiatures.net/madaboutcars/n_scale/Cabs/
The 60s GMC is a welcome addition. The Bullnose is nice too, but the GMC has so many possibilities in regards to dry vans, grain trucks, tankers, flat beds, etc, maybe find its way onto an Athearn pumper rear. I hope SM offers more of the 60s -70s stuff.
