Nikon film camera troubles?

I purchased a used vintage nikon n2020 and the curtain seems to be broken because it won't open and the blades appear to be bent out of shape and when i depress the shutter release button (set on bulb) and look at the curtain it bends out of shape even more. I was wondering if this is a small fix or if my camera is doomed or where i can go for help, thanks!

Added (1). Would it be worth it to possibly buy a body for parts and try and replace the curtain myself? And yes haha it was a good deal on ebay and the pictures were very detailed and convincing.

Oh, dear.

Another situation of buying a used camera without being able to first inspect it and make sure it still works.

eBay?

All you can do now is either return the camera to the seller and get your money back or spend a lot more money having the shutter replaced or repaired.

The shutter is wrecked and needs replacing.

It's major surgery. Can be done if you're good with fine mechanical work. Finding a service manual somewhere would help a lot.

Getting a decent film body in good working condition will be cheaper and faster.
