The guy basically killed much of the value when he decided to bend the bolt.
If it is does not match the action, then the value was already reduced quite a bit, even before he 'bent' the bolt.
Such "bubba'd" guns remind me of the classic GI vintage M-1 Carbine in the rack at Whittaker's (n.w. KY) about two years ago.
Some previous nit wit owner had painted the gun green.
