I found a heater that is made for the xk120 and have dismantled it and refurbished it. For the most part it was in pretty good shape and generally needed to be cleaned, lubed and repainted. The core is holding pressure but it is 6o years old and I may replace it just because. The motor was dragging but once the bearings and brushes were cleaned it does fine. Now if I just had a car to put it in.
