3 Brand New in the packet and 1 second hand scavenged.
These are probably impossible to get now and probably no one knows what they fit in. I actually forget what model they fit in but if I get out all of the manuals, I could probably work it out but I don't have the time left.
So hopefully they will find their way to someone that knows and wants them. And I don't have to throw them in the rubbish.
