Being looking to try and get a couple of gaskets for my Protector and have been banging my head against a brick wall trying to get through to the company themselves in Eccles. Their online shop is also offline at the moment.
http://www.thewandofscience.net/ which has an awful lot of spares for all makes and models.
Very resonably priced too - pair of gaskets £2, flints 50p each and even got spare set of gauzes for £20.
If anybody is trying to get any spares, I'd fully recomend them as they asnswer back quickly and should be able to sort you out !
