The gun was made in Brazil and would resell under $100.

Less than $100. SS Kresge is the original name of KMart. I just saw a S.S. Kresge 151 12ga for sale for $85 on a site that seems to price its guns a bit on the high side. Here is the related description: "$85, S.S. Kresge 151, 12 GA, 90% blue, excellent bore, good stock, 28'' barrel, 2 3/4" chamber Full choke. Light surface rust spotting on metal. Wood shows minor dings and scuffs with finish wear."
Possibly your best source of parts would be a junk Spesco mod.151.

Ensure that the gun is unloaded! With the gun closed, pull down on the forward end of forearm. It is held in place by spring pressure and will detach without tools. Now open the gun and the barrel will detach. It's that simple.
60-100. 100 if perfect.
No much, I think. It's a "out of line" gun (discontinued). You can find out it in some dealers about U$50 . But it's a reliable gun, if in good condition.
151 is Manaphy. You can find it in the Pokemon mansion on the book in the room where mr. Backlot is. \ Hope this helps:)
