As I stated on the thread, "Jack Zwickey Has Passed", Jack wanted to know if I had found any Black Diamond broadheads among Hugh Rich's collection. I didn't. If Hugh had any, I have no idea what he did with them. During one of our phone conversations, Jack said he would pay up to $100 each for a Black diamond. You better know I searched, and searched everywhere, to no avail.
Here's the letter Jack sent me.

Jim, the letter pretty much says it all. High demand and, in the beginning, a one man operation. Not exactly a high volume operation. No chance of keeping up with orders on a timely basis. Make it and send it on its way.
Here's the article Jack sent me. It's 11"x14" and doesn't fit on my scanner, so I had to scan one half at a time. You'll have to hold your tongue right to read it.
A very cool piece of our history. Did he mention how he, of all people, came to not have any?
