Over many years springs will take a 'set' and lose their original camber and need replacing or re-tempering. Will the oiled, greased and bound springs last longer than a set left untouched? If not, might there be no point in messing with them? Are the zinc inter-leaves found only in Ulster springs - and what's our best guess as to their function? Reducing wear? Modifying the damping characteristics of the inter-leaf friction? Improving the ability of the spring to flex? Or something else?
