[Closed] Trek 7000 frame......Warranty

Got a really old trek 7000 frame (1994ish i think....), which i've been using as a commuter bike...

No big shakes until i went to change the brakes and found a massive crack through the downtube.....

I discussed this with Trek (and looked on there website) who believe it or not would cover this on warranty, if i can provide a receipt...

Well, its been 18yrs and i've no idea where the receipt is...so thought i'd stick something up here to see if anyone has a recepit??

Bit of a long shot but figured i'd give it a go.....

cheers
