This is a more unusual make of carbide Mortorcycle lamp from the turn of the century. Water dripped in from the top tank onto carbide in the base tank which then created a gas to power the lamp. This is one of the earlier designs having faceted red and green lenses on either side. The front opens and clicks shut, the front glass is intact and the burner present too. I have cleaned it up as seen but this could be improved further with an evening of TV watching and some fine wire wool and brasso. The only thing that could have an extra pin fixing is the name plate at the top. Altogether a nice lamp for any enthusiast or present for a biker!
