Internally it appears to be in almost unused condition. It has been resprayed in gloss black.
As it is 6 volt it has not been tested.
Its age is unknown, but is probably pre-1939.
A 'Ducellier' 12 volt regulator. Age unknown, but believed either immediately pre-war or, posiibly post-1945.
It was fitted to a 1920's Amilcar and was removed around 12 years ago. It was working when removed, but has not been used or tested since.
