My sister sent me a link to this post she found when she Google'd dad's name.
If you haven't already....
Jim is right, Steve would have the most info on that rifle. Dad (Darwin Hensley) didn't keep a lot of details in his records, at least not much that can be easily found by me. Give Steve a shout, he worked with dad on several rifles and was one of his favorite metal smiths.
I'll mention this post next time I talk with him, it will please him that he is still remembered for his stock work. I learned a lot from him and am grateful for having him as a father. Just a great guy overall.
Take care,
