Another Oldie!

I remember that this car of my father's was dark green and the first part of the number plate was COW--- which was often commented on or pointed at, being the only green COW on four wheels in Dorset! I don't remember the make of the car though...can you help? It was probably quite old when my father bought it! Left to right: Raymond, Terry, me.

It may be a Morris 8 Series E. Thank you George.
