In that era bikes were often sold without lights.
1930 you could still fit acetylene lamps if you wanted; horns would have been bulb horns, and like the lamps would not have come with the bike, nor a speedo.
This is the sidevalve? regarded as an economy model at that time.
You could have fun picking up lamps and mixing makes such as Miller or Lucas and no one can tell you different.
Lucas, Miller, Beta, Bosch P&H were just a few makes on offer, a well as from James Grose, Halfords, Pride and Clarke all sold their own stuff.
Won't be cheap, any of it. You do not need lamps on a vintage bike, or you can always fit LED push bike stuff for safety.
