My toilet seat broke, but because of the age (over 40 years) the fixing screws were rusted in and the porcelain bowl near the screws very thin. We were warned the bowl might brake which meant new plumbing and new toilet, cistern and wash basin because unable to match the colour. Rusty suggested using a very thin blade to saw through the old screws, It worked!! Then he carefully opened the packing from new seat in case not suitable and needed returning. All went well, and save me a great deal of hassle, mess and money.
