Rear hub removal blues

[40cpe]

One of my rear brakes on the '38 started dragging/not releasing all the way. I dedided to tackle it today since it is a little less humid. I had bought a Mitchell puller several years ago when I bought the car and used it to pull the drums and service the bearings. It worked fine then. Today I kept tightening it without the hub moving when I discovered this. I don't know what to do now. I've been looking for a KR Wilson knock-off and don't see any for sale. At least the groove in the hub doesn't appear to be damaged. Any thoughts?
