WFC Peep Sight for the Stevens 325-B

I lucked out and found on eBay a vintage WFC peep sight meant for the Stevens 325 / Savage 340 and snagged it.

This should noticeably improve the practical accuracy of the rifle compared with an open rear sight. It's missing the mounting screws but I just checked the threads on the rifle and they are 10-32, so sourcing a couple suitable cap screws will be easy. I may have some in my shop but if not, Lowe's or Home Depot will have them.

Since this peep sight design hangs off the back of the receiver it's a bit more vulnerable to damage than a barrel-mounted open sight. So, I want a backup. I have a Marble's #95 sight on the way from Midwest Gunworks. The #95 has a folding leaf so it will be down and out of the way of the peep sight.
