I will change the return policy. I have over 100 transactions on Ebay going back 10 years with a perfect feedback rating. Most were somehow firearms parts related before they stopped all that. I probably should have mentioned that in the Gunbroker listing.
The stock is what Treebone Carving sells as their Sharps mid-range copy and that is what I had in mind: a black powder target (not silhouette) and hunting rifle. The firing pin was already bushed and I chose a Krieger barrel of good steel (4150) so that it would also be safe with any reasonable smokeless load.
