Hi - New to this site trying to figure it out. I have a savage model 25 22cal S. L. Lr. octagon barrel s/n 35xx made 1925 to 1929 open rear sight front sight with ring that folds down to reveal another sight

top tang has two holes for peep sight and four holes on top flat of barrel for scope not sure if holes are factory or after thought or what brand or numbers would work.

what I am mainly looking for is a place to buy forearm and screws mine has one hole on each side of slide. Or dimensions and maybe a picture to make a new one as there is not a lot of any info out there
any info would be helpful thank you
