Vintage Louis Vuitton speedy bag from 1970s or early 80s

Pre owned by my mother - purchased in either the late 70s early 80s, so I don’t have a receipt. Predates the LV stamped date code. I’ve tried to take pictures that convey the authentication such as brass clasp and symmetry to pattern. If you want to see any other pictures to authenticate, please let me know. Please notice the stitching on the handle needs to be fixed. The bag comes as is.
