My father just passed along a gun from his youth and I'm not familiar with it. It's in good condition and good working order.

I'm wondering how old it is? Also, it's missing the bead on the front sight and I'd like to get it replaced if possible. Where can I look to find a replacement? A little help would be greatly appreciated!

It's a Savage Arms 22 Highpower model 1899, lever action – Serial #135116

Thanks!
