Vintage Gucci bag

Vintage Gucci bag. Bit of wear in the corner shown in photos. So my neighbour gave me two vintage purses that belonged to her mother. I don’t know how to check for authenticity but she is sure they are authentic. Here’s what a read on the internet: Vintage Gucci bags from before the 1960s had model numbers on their tags. Around the 1960s some bags would and others would not have a model number. Around the 1970s Gucci bags had no serial or model number and just the Gucci script in cursive.
