Well HMV books say model 2 so let's go with that. Nice oak horn with gold lines. It has a Exhibition Junior sound box book says fitted for a short time after July 1916. A nice two spring motor book says those added during the great war period. It had patina(rust) galore so I cleaned it up. I will try to show some before and after 'patina' was removed. ha ha A nice find and so happy to have it. I hope you enjoy looking at it too.
