Authentic Louis Vuitton Speedy

Louis Vuitton monogram speedy 25. I don’t see the size on the tab, might have rubbed off since it’s a vintage piece. Photos of Measurements are posted, it might be a speedy 25, not too sure, maybe a 20. - It is in great condition, aside from the darkening of the vachetta and a little dot on the canvas ( shown on pics) -zipper pull still intact -zipper closes and opens with ease -inside is in clean condition -serial number is shown in one of the photos -it is a wonderful bag, just needs vachetta cleaning or replacement.
