I'm sorry to have to ask this, but wasn't it November of '41 that the reinforcing lip was added to the accelerator? (Lost some of a hard disk a while back B4 migration.) And wasn't Winchester a little bit later? (Show me the money gripe?) I'd appreciate it to sort out my SA and Win oprod catches time periods, many thanks for help from those that didn't flub on saving their notes (like moi).
