Was going to send this auction but thought I'd put it here for a week. This is from the first run of 475s that came with the 22" barrel, not the 20" that they currently use. I bought the gun as unfired and that's just how it remains today. Not sure How many they made in this barrel length, but John Linebaugh believes it to be less than 150. If anyone knows for sure feel free to correct me.
