That's not 1st-gen, and the rear triangle should be chrome. I sold one recently - https://www.retrobike.co.uk/threads/1991-fisher-cr-7.492796/
1st-gen was 1988 and had a 1" steerer & chainstay roller brake. The oversized "Evolution" started in 1989.
Nobody buys one of these for the frame :)
If it was local I'd maybe take it for the fairly decent XT cranks/rings/pedals but it's two hours each way so meh.
