The true oilite bushes are porous. Not supposed to be reamed but I have encountered undersize so presumably were available finished. Lucas dynamos on post war cars had these and many were very neglected but not a source of much trouble. The properties of oilite are remarkable. (On other makes the prepacked ball race at other end gives trouble after 60 and more years of no attention. Seven ones get doused in oil )
