Don't know anything about said T&V show. Never heard of it and likely will never see it.
However, I do know Roger has 2 model 70's left, I don't know what they are.
He is interested in Bespoke scatterguns now-a-days.
I think he's down to one. I bought Roger's '47 .270 WCF transition, which he had kept for over 30 years. Based on my conversations with him I believe his last model 70 is a pre-64 custom .338 Win Mag that he had built by the Winchester Custom Shop while he was writing his book
The Rifleman's Rifle. The stock design was fashioned after Serial Number 500,000 featured on the cover of the 1961 Winchester catalog. This last rifle has really nicely figured wood.
