Re: '31 Murray Body Number Plates
 

Concerning grey painted engines in Canada, there are two examples I know of.
An early 35A, one of the first sold new here in NZ [ CA 8625, body F359 Ontario] had grey on the engine ; it was a very good original car before restoration.
I also have a copy of a Restorer article on a very original ,low mileage 1931 Tudor [CAP 6125] from Ontario , which had an engine colour described as ''ditzler Battleship Grey''.
My own car [ which was mostly assembled in Canada] had faint remnants of Ford green still visible on the waterpump. It must have been a thin once over original Factory job.
The grey would look different/good, but somewhat controversial.
