David..it is great fun to talk with the old timers. The things they did and saw are priceless. Just remember, those times were different than "our times" right now and some things were done differently.
There were a TON of different broadheds available over the years. If you are interested in researching many of them, a gentleman named Wade Philips put together several textbooks about them. Pretty interesting stuff. Full size pictures and good info. They are not cheap...but they used to be available on ..that bidding site.
Cliff Zwickey supposedly was making broadheads in the late 1930's and the company still makes great heads today. At one time Fred Bear contracted Zwickey to make broadheads for him. He killed his first moose with one. Zwickey's early broadheads were black and that gave the name "black diamond".
Your description of the "Butte" broadhead was not enough to know for sure. There was a series of heads called "Butterfield Brutes" which I happen to really think highly of. Unfortunately they are not readily available anymore.
Hills Hornets, as I recall came in a three blade and a two blade version. Don't see any reference to a four blade version. If you have a camera and visit the gentleman again, please take photos and I am CERTAIN, that some one here will be able to tell you about the heads. There are a number on the site that actively collect old heads and are a treasure trove of knowledge.
Have fun and explore !
