Answer
Hello Raymond.
  I will try to answer your questions. Your shotgun was made by the Brazilian Cartridge Company around mid-1970's. It was imported by F.I.E. (Firearms Import & Export),a company out of Miami, Florida. They were sold at discount stores. There is no significant value to it, other than being a fairly good hunter.
  The company is now known as C.B.C. and they make ammunition for mostly military use. Check out this web site. It may be an exact model of yours. www.google.com/search?g=cbc+model+sb.
You can also get the history of C.B.C. by going to www.cbc.com.br/explorer.htm.
  This is about all the information on your shotgun, so I hope it answers your questions and thank you for letting AllExperts help. Charles Gage
