That stock DID NOT break that way from a simple "fall over". The fact that the buttplate was taped on is PROOF that the rifle was dropped vertically on its butt, causing the wrist to shear along the grain.
Had it broken from a simple fall over it would have been a short, cross grain break. It also would have broken in a different location, likely in the area of the lock mortise as that is where the most wood is removed and in all actuality the weakest area of the stock.
Had the rifle been undamaged he would have pressed for the entire $3500.00 in damages, the fact he so quickly settled for substantially less tells the tale as well.
What knucklehead puts a pricey item on a standard floor display to me is curious as well. He took on an implied risk by doing so if in fact the rifle was undamaged, one of those "What did you think would happen" moments.
This thing has red flags all over it.
Agreed on camera footage, I would have demanded it. I would have refused to pay as well. He can file a claim on his insurance, I will pay half the deductible seeing how he took the risk of putting a valuable item on floor display.
Let him call the cops- it's a civil matter. Take me to court and prove your case, I get to demand discovery so any video footage would be called.
Hope he bought you dinner cause you got fucked.
It can be repaired by a 'Smith who is knowledgeable in muzzleloaders and traditional repairs. It should be glued and screwed with brass screws, the heads left proud of the stock and then filed down flush with the stock. All what will show is what will appear to be brass pins. For a traditional reinforcement a wet rawhide wrap would be appropriate albeit a bit out of place on an Ohio/Pennsylvania style rifle.
