Hi Fancypants,
Sorry din't reply sooner, but had work commitments.
Will take some extra pics soon for you/people to take a closer look, but nothing to exciting on the back of the pic, just lots of dust.
but i dont know what to look for.
As for the history of it, all i know is that it's been in my Dads side of the family for years, and had been handed down to me.
Thanks Wayne
