That TK-41 refitted with modern camera/viewfinder would have came from History For Hire, they have a few of them
https://eyesofageneration.com/teleta...-a-grand-tour/ . Back in 2003 R&B group Outkast used one of those prop TK-41s in their music video "Hey Ya"
https://youtu.be/PWgvGjAhvIw?t=194 as well as a TK-60 earlier in the clip, I asked about that clip and was told the cameras were modern camera/viewfinder fitted and came from History For Hire. That TV in the background is a B&W set, not colour, colour TVs back then were round tube.
