I think this is for a YamahaFs1e Also maybe a dt125 dt100 not sure it has a bulb holder and bulb not tested, reflector is good shell is a bit rusty on the back but solid I am sure it would clean up nicely for a new coat of paint, it chrome rim has one flaw will try to picture it tomorrow not to bad though. measures approximately 4 1/2”across glass section.
Any questions please ask
Both fixed nuts on the inside have come loose but obviously when bolted in position it would hold ok.
Any questions please ask
