Vintage canvas & brown 'leather' camera (?) bag

Awesome Vintage canvas & brown 'leather' camera (?) bag! I think it's a camera bag... I've used it as a regular bag though😊 not sure if its leather, brass detailing, no let for the lock. Small light pink stain- really can't be seen while wearing, there is an outer front pocket under the front flap (under front buckle) as well. Pocket inside & a buckle to keep things in place (like notebook or tablet:-) Tried to capture everything, see pics - they don't capture just how cool this bag is though😊
