eBay! It's all the same part, marked up by various vendors. I have a 1950 cad and paid USA parts supply around $150 if I remember correctly, only to see it on eBay a week later for around $70.

Looks the same as the 41 type. I wonder???
Fusick may have them as well, just be careful with some of the eBay sellers promoting their product will fit and they are totally wrong...! :o
