I have a drain plug but right beside a frame tube and oil will take a long time to drain as it has to pass the chain adjuster. However, it is variously described as a greaser/oiler. Strange to have 2 different length nozzles and they are tapered off to fit into a hole in a shaft. No dents or scratches and looks as good as new. It was a fiver so i had to have it.
A lot of this engineering gear turning up at the local boot sale these days. I dont think many people repair their own vehicles now judging by all the socket sets i see.
