Hi all, I'm having some trouble dating this bag. Perhaps it is home made or been home repaired and that is why I'm getting conflicting info from it. I believe the leather is machine tooled as the same mistakes repeat on the pattern. The Lightening zip I have dated to the mid 30s, but the Aero zip I'm getting all sorts of ages. According to a past post on here, probably 60/70s. No tags inside. I'm pretty sure the inside is made of thin leather. I've circled where the mistakes are. Any idea please brains trust?
