ANSWER: Hello Foster.
 I really need all the information from your shotgun. Is it ' Iver Johnson Arms & Cycle Works ', or ' Just Iver Johnson '? Is it a ' Champion Model ', or has it another name? There are some differences between models. I am sure I can help if you provide this additional information. Charles Gage

QUESTION: im sorry for not suppling the information the first time but upon lookin at it better  it is a "ivers Johnson Arms & Cycle Works" and it is a "Champion " model.   it also says '12 guage full choke barrell and lug forged in one'.   is there a way to find out the year by this info?

Answer
Hello again, Foster.
 The closest I can tell as for year of manufacture is 1909-1918. It is really difficult to pinpoint, since there were very few changes in these shotguns over the years. I suggest you google ' B. Goforth.'. He wrote the book ' Iver Johnson Arms & Cycle Works 1871-1993 by W.E. Goforth ', but he shared much of his knowledge on Internet forums.
 I did find the parts you mentioned at Numrich Arms www.gunpartscorp.com. The parts numbers are 470500 and 583750.
 I hope this answers your questions and thank you for asking for me. Charles Gage
