Hi Alan
Not sure exactly what referred to but was aware of the commercial gadget, but most amateurs are stuck with a square, level, protractor or, if really daring, packing and trig tables.
With hindsight the castor of my car would have varied over a range over the years but I did not notice any great change or difference or from another I owned briefly.
