Savage Model 4S - help needed

Hello Folks. New here.

Bought a used Model 4S recently. It has a checked walnut stock, and should be around 1937. It had a Mossberg No. M4D 4x scope on it, which needs an overhaul. It also has a Redfield base for a receiver peep sight, but no sight itself. I'm not sure what's stock and not on this one, and I would like to find and install the receiver sight. I've been advised that the base is for a Redfield 102, but the 102's I see are for specific makers, and none I can find are specifically for Savage. It's also completely missing the ramp rear sight, which I'd like to replace as well, if not with the standard, maybe with a flip up.

Here is a link for a photo album, and any help you folks can offer on identifying what I need and where to get it would be really great.

Thanks!

Any guidance would be very much appreciated. There were enough of these old Savage's out there at one point that someone's bound to be an expert?

Thanks!
