Looking at those cars....and not finding any original writeup/explanation, I see Athearn metal cars. I spot the folded corners...and the silly paint colours we never could quite match to Athearn's originals....(410M?). Last NYC Pacemaker Athearn Metal Boxcar kit I built was just like those...spent some time tring to match paint on doors and ends. How have your Zamac detail bits held up? Dave
