Nothing on google Bob, but did find a correct name for the "bulge" rocker panels....Chevrolet's new "Concealed safety steps"
My vin tag date is 04, built at the Tarrytown plant, so I kinda doubt it was leftover parts, plus the old ads claim a whole new model for 41 with a Fisher body....mine has an oval brass Fisher tag on the door hinge post.
But then again what else COULD it be?
I found a Chevy style number chart for 1946, but couldn't find 1941.....but if the numbers are the same (1227B), this coupe means business!
She's a 1941 Special Deluxe Business coupe
