Very sorry to hear about Michael Petrov's passing. I am Jules La Batchni's step-son. Along with my mother, he raised my sister and me from 1960 to 1970 in Santa Monica, CA. While growing up I watched hour-upon-hour as he hand-crafted custom guns for sale as well as commissioned by many a Hollywood star. Jules taught me to shoot as well as how to play the saxophone. Jules did not work for Pachmayer during my time with him, but I did hear stories of him working there prior. I spoke several times with Michael Petrov providing him with intimate, first-hand accounts but we then lost touch. I hope that someone continues his research on Jules or that I might come to get copies. If anyone is sincerely interested in learning the truth about Jules La Batchni - first-hand accounts from someone who lived with him and worked in his shop for ten years...please feel free to reach out.
