You got ahead of me. These were going to be my next post. These are what I believe are the Madador II heads. I say this because of the article in our newsletter years ago and from ads. I can not tell from the pictures, but are they all 4 blades? The bottom two kind of look like the other set of blades might be different from the set of blades we can see. The Madador II had the flared/straight ferrule and also larger threads on the tip. The blades now had a sloped back edge and were all stainless steel.
In addition to the standard 4 blade, 2 blade, field point, they also had a new Turkey Thumper and practice blades.
Here is the Madador II with practice blades
Here is the Madador II for aluminum arrows. According to ads this came in three sizes 2016, 2114/2117, and 2216.

Hope this clears up the Madador and Madador II models. From here on it is going to get more interesting and I hope Mark will be able to shed light on the next models I will show.
