Vintage Glass Beaded Fendi Bag

I am not entirely certain as to the history of this bag. There is no serial number or hologram which would indicate it was manufactured before the 80's. It feels like it weighs about 2lbs (not actual I have not been able to weigh it). I have only been able to find 1 other like it. The difference being the snake skin is pink and the top two panels are turquoise instead of black. The bag measures about 13" wide 10' long. The exterior is covered in different coloured glass beads. With the bottom two right corner panels having a reflective surface in/behind the circle. The lining material feels to be satin and is unlike any other I have been able to find online, in that it is patterned and not solid like the others I’ve seen (picture 3). If anyone can tell me anything about this bag As far as it being an authentic or not I would appreciate it. I never even knew what / who Fendi was until I found this bag (thrift shopping) and looked up the name on line.
