Gun Broker 929244010 has a complete set of parts including forearm and stock for a M220 Trap gun. Missing is the receiver. I really hope this rare gun was not broken up for parts and ease of shipping. The stock has a chip missing where it joins the action, otherwise, I would bid on it. I already have a Trap stock in the same condition. In my years of research on the 219/220, up until a few days ago, I had only seen 5 of these Trap models for sale. I purchased 3 of them in 12, 16, and 20 gauge. I was out bid for a 28, and .410. A few days ago, and new member to our forum advised me and sent pictures of his 220 Trap model. This makes number 6. I will have details and pictures of it in the next printing of my book. It is a little bit different from the 5 others I know of.
