Hello and welcome to the forum!
Your hood is likely quite repairable. Hopefully it's conditiopn is not a result of an impact that may have caused damage yet to be discovered.
My advice is to carefully remove the hood and focus screen.
Once removed, you will have access to the mirror and rear element of the viewing lens as well as the bottom of the screen itself.
If non are severely scratched or eroded, you may have some luck improving the view with a thorough cleaning of all surfaces.
Be very cautious when cleaning the mirror. Google for a video tutorial and take your time.
If the mirror is in bad shape a new screen from Rick is not going to help much if at all.
As for the bent hood. Does it look like you can tune it up? Donors are out there if not.
Here is a DB with serial numbers matching to model names/numbers
. It will help you find a proper donor.
If you find your camera is worth sending in by all means do so. If your efforts uncover a camera unfit for restoration well... you have a parts donor at least
