Thank you Hyacinth. I've learned to ignore claims about bags from the 1970s unless it's verified by the ladies here. I figured it wasn't from the 1970s but wonder if it's a form of false advertising for those who can't tell. 20 years is a big difference.
Some sellers probably deliberately lie about the age, but many are just too uninformed or too lazy or careless to even try to figure out when something was made. And unfortunately there's at least one " history of the creed and serial" guide by an Ebay seller where almost every single date s/he gives is completely wrong, often by ten years or more. That "guide" seems to be a Copy & Paste of an earlier guide which also had the wrong dates and information and was posted at an outside forum under a name I've never seen before or since. I won't mention the seller's name, but strongly recommend that any guides from sellers named after motorcycles be ignored.
