About three years ago, one of the auction houses (Rock Island?) had a center fire and a rim fire they attributed to Howe. Neither rifle was signed in any way. I bought the .22 on Springfield M22 action, arsenal barrel; it had tiny little ivory pins to fill the several pin knots in the wood.

I have since sold it, so don't have photo availability - however, the FFL holder who receives for me with is a "lurker" here, and he might remember where it went. If you know, Tom, please call me.
