Actually it is a Johnson and Bye Defender. Mr. Bill Goforth is the real expert on Iver Johnson's. I have his book open in front of me, but rather than confuse the issue I will let him expound on the subject. These were inexpensive fire arms ( Small frame does not even have rifling), selling when new for two or three dollars. I will let Bill make any guesses on the current value. He will check in shortly.
