There was indeed a video series of the collection that Harry himself starred in showcasing his lock collection. I doubt it was comprehensive and it was a tough time for Mr. Miller when he made it but he muscled through it as he did with everything by all accounts. It is copyrighted 1992 by Mark S. Scuderi who I think produced it. The set I have is: 1 timelocks, 2 combination locks, 3 combination locks, 4 combination locks, 5 combination locks, 6 manipulation proof technology, 7 miscellaneous. It’s on VHS so it’s hard to scan through. Each one is about 90 min long.
