I know how this title reads so will start by apologising 
Dh trying to fix the downstairs toilet lifted the lid of the sistine and it slipped out of his hand and broke.
Problem is we rent and are due to leave in July. So manic check online we discover the toilet is over 15 years old and no longer produced.
Is there a shop anywhere that specialises in old no longer produced parts? The actual toilet functions well (apart from an annoying tendency to block but this is usually easily fixed by flushing and pumping -what dh was about to do when it happened)
Annoyingly the toilet is not a standard shape or colour. Its kinda square with an almost grey pebbledash appearance.
