I've decided that I'd like to try and find a Speedmaster as close to January of 1985 as I can. I realize it might be a Sisyphean task but I'm hopeful the OF community can help. I wondering if folks would be willing to share their extract serial ranges if they have them for Dec 1984 through March of 1985. I've already tried ilovemyspeedmaster.com but the data is sparse for the mid 80's and I've gotten conflicting answers. Thanks!
