Many years ago I had this problem. Fortunately we had a friendly toolmaker that I used for making parts for the factory’s machines where I worked. He was able to grind out the inner race fairly easily. If I remember he used a 3 jaw chuck to grip the inner track. I reckoned that absolute concentricity was not essential as the bearing only moved about 45 degrees.

Velocette also use taper roller head races and I think their spares scheme offers the correct bottom race for £44.50 according to their spares list.
