I've known Michael for more than 40 years. We traded guns a bit but information much more; they were pretty lop sided trades. As many of you know, before he retired ten years ago, he worked an oil platform off Alaska. Not being inclined to play cards, he used his many off duty hours to research rifles/gun makers.
As xausa and eightbore both reported above, he wondered what to do with his research materials upon his death. The Rifled Arms Museum idea died with Mark Benenson, so that is out. I think the Cody Museum is perhaps the best repository. I hope that wish can be fulfilled.
When we last spoke less than two weeks ago, we knew he was on a steep down hill, but thought there were a few months left to finalize details. Obviously, we were wrong. I was going to send him the Zischang Borchardt .25-35 he admired from my collection to let him have 24/7 access to it, but now even that option is gone.
We have lost a good man!
