Latest Development: Gillian called me this afternoon - such a sweet and helpful lady - and after the usual digressions about the weather, Wimbledon (bags, of course!!) etc. we got onto the matter in hand and she said that they would be prepared to replace all the old magnets with the new style ones.
Yeay! - really pleased actually - and, although that option has already been considered in this thread - and I said I wondered if her integrity as an old girl would be compromised - actually I've come around to the idea that I don't think so - it's splitting hairs really isn't it, especially as the "newer" magnets have now been around for a good few years anyway - and, in the scheme of things, Roxy the style isn't really "old" Vintage anyway - and if it extends her lifespan, then it must be good. Of course I'll have to pay for it (hopefully not too much!)- but I think I will go for it.....
So this clears up the mystery of whether they did change the magnet when she initally went in - of course they didn't - she apolgised and said there had been a communication issue and that they really don't stock, source or use the old ones anymore - and that really I should have been told this when I picked her up after her 1st (supposed) repair.
So all good....and thanks to all of you for your moral support and encouragement - it is so appreciated!!
