Yes, it was Mark Lambert. The show was so good, it would help many restorers of cars of that era including the 40s and 50s even. I am shocked to hear that he is gone. He was young, so young! Sad! I did a search for Mark Lambert on YT and found the show. You can still watch it, but not for free. You have to sign up for MAX tv for $16.99 a month, cancel anytime. I could watch all the shows in one month, so that sounds pretty good even though I have a 48 DeSoto.
Just look up Mark Lambert 1938 Packard on Youtube.
