Well I must admit I never realised that an old wallet could be that valuable you've opened my eyes.

I do have an old piece of kit here that I will use to read my old hard drives. It's an old Compaq Desk Pro (in perfect working order) running Windows '98. This will be an adventure back in time for me as I'm sure I'll discover other files that I thought I'd lost.
So I'll keep you posted as I search for the 'needle in a hay stack'!! Wish me luck.
