No, he did not. It could be a registered DEWAT. We can't tell from the info provided and neither can you.
When I worked in the 109th Congress we were sponsors on a bill to allow unregistered war trophies of deceased vets to be registered by heirs transfer tax free on filing on an affidavit that the item was a war bring back, that the vet was deceased, that they were the rightful heir, etc. The bill would have made guns that might fall into the black market legal, registered, and safely owned. It made too much sense to get passed.
