Thanks guys! I did send pics to the seller and they were very quick to offer a refund to the sound of 13%. Which I was quite happy to accept!
I can see what has happened the box didn't have tie downs in those days and the toy has rocked forward in the shipping process (ruff as guts!) cracking the 23 year old window! Doh
It's just nice to get what you pay for. Unfortunately these things do happen and it wasn't badly packed just bad luck.
It is still a holy grail item for me and will be displayed with pride.
