A Magnette, indeed, but it can be a 1954+ [ZA] or a 1957+ [ZB]. If we could have a glimpse of the side chrome trim it will be easy. Usually, the [ZB] came with additional fog lamps attached to the overiders, something that not all the [ZA] cars had.
Unfortunately the front wing is not visible and it would be the most important part to be seen. Nevertheless, it's not usual to see one Magnette on wires and I like particulary these painted ones.
