I agre with Shane, it looks like a #4. You can verify by comparing sized here.

I wouldn’t call the dish that serious. You can find several blogs here on restoring planes, I’ve got one that shows some worse looking specimens that came out great.

I agree I would sharpen it and give it a try. I dis-agree that its not worth fixing up, especially if it has sentimental value. You can make that plane work as well as any if your willing to put in the time.
