I would also have said early 50's, something about how low cut the sides are (the more revealing - the later, in general) and the logo - is that a sticker or stamped?
It's a good size - a UK 6 is the bestseller here (it's related to the average height nowadays) which yours are not far off - that sort of damage can certainly be re-inforced with a sewn patch to the inside but you want a good repair that won't create weaker spots where the new stitching is - that only comes with a decent cobbler!
Personally, I would try selling them as a set first with a good price, then split to bags & shoes if they don't move.
