FWIW.....I think the laminations in the later Westinghouse switches are the same design.  I know someone here in past laser cut a batch of tank motor laminate duplicates, but I "think" there is a possibility I may be right. Stamp steel Westinghouse stumps are fairly plentiful out there to rob a switch from for the laminations.

David Hoatson was the one who reproduced them and sold them in past here.  I have a mix of 12" and 16" Westinghouse stamp steel switches from stumps in the image. I have a tank switch dead center for comparison.  It appears the 12" stamp steel switch laminations appear to be a match. All you have to do is use the same number of laminations that your tank switch originally had. If your a few off big whoop. Just make sure they each have a thin film of insulating varnish between them to control eddy currents. 


If your 2 speed tank winding is shot all you need to do is get the correct gauge magnet wire and wind it by hand on a form to fit inside the lamination stack for 4-5 ohms for your second low speed.

Psssssssssssst........I wouldn't exceed 5 ohms and risk fan motor RPM falling low enough to engage the switch contacts for the start winding.
