Your bag is from around 1947-53
Please leave your pics up so that when people view this post they can see why and what/which bag you and I are talking about
This is the original model for the Lady Lock BTH AW13 and you should never ever sell it(actually not kidding
).
The exterior leather certainly needs proper conditioning (never mind the scratches) it is in danger of cracking unless it's done. I would recommend very gently cleaning (using hardly any water/liquid as in virtually none) and then a tiny amount of no-colour, old fashioned leather fat/cream every 2 weeks for 2 months (so that's a tiny amount done 4 times) and send back photos
I've been waiting with bated breath for your response! What a great find!
