I was talking to my mom about straight razors today and she said she thought she had some from her great grandfather that is from late 1800's to early 1900's.

She gave it to me but it has a bit of a chunk for lack of a better word missing from the last quarter of the blade. It's got a gorgeous spine on it and look nice and I was wondering who to talk to about seeing if anything could be done to fix the blade.
I'm not thinking it can be fixed and if not I will save it as a keep sake, but if I can, I would love to get it to shaving order again.

I'm lost on who to talk to about restoring it and any advice would be great.
Thanks everybody.
