This bottle has a British registration for 1926 (725384) and a Swiss musical movement. Material used in the movement suggest a date closer to 1950...
If anyone is going to the records office it would be good to know who registered the design... I expect it relates to the way the base indent is moulded to proved a recess for the movement and its spring clip.
The transfer decoration is unusual in the amount of enamel and it might be part hand painted. This might push dating back to pre WW2.
