Iver Johnson 12 Ga.

Question
I bought an old 12ga. at an auction and can't find any info on it. I was wondering if you could help. On the top of the barrel it says "IVER JOHNSON" and under that "PATD.APR.2'01.APR.15'02.PATS PENDING". On the left side of the frame it has "IVER JOHNSON'S" and under that "ARMS & CYCLE WORKS" and under that "FITCHBURG.MASS.U.S.A.". Serial #J94196. It has a lever to take the hinge pin out to break it down. That is all thats on it. Please help!! Thanks.
