my experience with the rear sight screws as well. They look so original I forget which of my rifles have them.
As far as the forends go I've had good results with a KCA member. here's the website:

I've used them for hand-guards as well and the results have ranged from excellent to so-so wherein I had to do some shaving here and there.
A decent sporterized stock just went off on eBay for 128 bucks, so with some labor and less that 200 you could have had a reasonable stock.
Middle bands will be 30-50 bucks and the front band will be between 50-100 bucks. It's not cheap but its fun and you have the satisfaction of bringing a rifle back from the scrap heap of history. ANd, in a sense you will be buying your rifle part by part so it's kind of like an installment plan. That's the only way I can get rifles into my collection these days.
Keep us posted.
