I don't know, the chain is not too dissimilar to the ones shown in the photograph Nicole posted, and there is a plain framed one on the left, so those parts look period to me, but I agree with Nicole that the lining appears more modern. I suppose it could have been relined and they also put the label back in (the interior stitching, though perfectly adequate, does look a little sparse/rough), that placement is quite typical of 50's/60's handbag labels btw. In this case it might be worth looking for labels from dated examples to compare.
