I have an unused Hillerich & Bradsby (yes, the Louisville Slugger guys) WWII walnut stock. I got it from my brother who got it from our grandfather. Worked all his life there. It's in pristine condition. Beautiful wood too.
Any suggestions on what best to do with it?
I'd like to get some hardware to go along with it. Any suggestions there?
Since you asked, if it's truly unused I would not do anything to it except maybe apply a light coating of raw linseed oil (flax seed oil is the same). It may be worth more without the hardware by leaving the butt plate screw hole and recoil plate escutcheon hole undisturbed.
If it were mine, I would obtain another well used HI stamped carbine stock and mount them together in a shadow box showing the "Before" and "After" perhaps commemorating your grandfather's contribution to the war effort. It's all about history. I think it would be a shame if it wound up as part of a "made up" restoration carbine. Just my opinion.
As far as I know, they only made stocks and hand guards for Inland (marked HI) and Standard Products (marked S-HB). I understand they also made billy clubs during the war as well (small bats?). They don't say anything about their wartime history on their web site but maybe you can contact someone there who can give you more info.
It would also be nice to know which version of the stock you have. Hillerich & Bradsby made type 2, type 3, type 4 and type 5 stocks for Inland. That way you would know which used stock to look for. Only Overton made the type 1 stock for Inland as well as all the other types.
