Hello all .
on the oiler that adorns a nail in the shed wall awaiting fitting the adjuster does not have a plunger working on the under side of the adjuster wheel , but has a piece of flat spring steel working on the outer rim of the wheel . it looks official there is not anything on the casting to suggest that a plunger could at sometime have been fitted. if this old twit was bright enough he would post a photograph Regards D F.
