I have documentation that Mr Henderson did the work on the shotgun & I have an appraisal for the shotgun already. The shotgun was engraved & bought from Mr. Henderson & has been in the family since. I will say that yes you are right that Mr Henderson did do knives and other items to include shotguns & rifles. He has done work for President Carter & Ford, as well as for Hank Arron & some other celebrities. At West Virginia University there is a Winchester Rife on display that Mr. Henderson did. That rifle was appraised at $50 Grand.
Thanks for the input, really would like to sell this gun. Glenn
