That one looks a little rough to me.
I brought it to someone's attention the other day to illustrate relative price of the 8-bore these days.
My intent was to note how much one would have to pay for something that looked to be iffy/sub par.

It might end up shooting like a house afire etc, but I somehow doubt this rifle's ready for a good run before it gets a checkup and a few booster shots.
Someone's obviously screwed with the locks, the bolts are gone and those aren't likely the original hammers. It's anyone's guess what they look like inside.

I wonder if the stock has been repaired, and if so how it's holding.

The forend iron doesn't seem to fit up right to the action, and the cover screw for the action pin looks a bit sprung.

The chamber/bore condition isn't noted, and I don't see a mould for it.

There's at least one blade missing from the rear sight.

I see a piece of brass in there, is this rifle even set up for brass cases? Is that a standard dim brass case anyway?

I'd have a lot of questions, want to do a lot of homework, and demand a good long inspection period for this one if I were interested. I'd have a date with the local X-ray at the nondestructive testing lab scheduled for the day the rifle arrived.
I'd be looking for issues with the lockup, cracks or repairs to the stock, cracks in the action, cracks in the barrels and excessive corrosion between the ribs (or any loose spots), bore condition, wall thickness, chamber specs and condition (have they been lengthened?), and I'd want to see what's up with those locks

On the plus side, it's a neat old bar action (not my cup'o'tea) 8-bore rifle, it's cheap, and it's cased (and at least has a sticker in there with the maker's name on it, although the address on the sticker doesn't match the address on the rib).
There's some tools in the box too, but it remains to be seen if they're appropriate to the rifle.

I've sent cased sets like this back to cabela's in the past.

My thoughts on this rifle are worth exactly what you paid for them.
