I missed the whole MTB thing but I can imagine where you are coming from, most of us can I am sure.
I am currently 'restoring' (I use brackets because I have to use parts I have rather than search at this time) a Muddy Fox BMX bike.
I was trying to buy a plastic scale model of a Muddy Fox MTB by Araya a few months ago om Ebay and the tie up only fell in to place recently, wheels within wheels. Look in from time to time and do not be afraid to post about old school MTB. There is cross over and there is interest.
See you soon I hope.
