The model 'B' Rochester has many faces and close but no cigar on the air horn and or throttle body specs. The late model 'B' has the bronze filter air horn. {manual or auto choke} is an option. The model 'B' specs I list has the 2 15/16 inch throttle body. 7024561 is the body for the manual choke. I don't think 2 15/16 throttle body will fit on your '41 intake.
My personal choice for the 216 / 235 inline six is the model 'B' Rochester.
Inspect and check if the carb will mount on the stud bolt pattern. If it fits, I will suggest rebuilding the Rochester.
I have issues with the complicated Carter. Hope I have been of some help. Good luck with your project '41.
