I don't know of a vintage Penny. I think you are thinking of the pocket purse 9755. It looks almost identical to the Convertible Clutch but is a little smaller, has an open pocket on the back and an open pocket inside (no zipper). It is 9 1/2 by 5 3/4 by 2 so it is bigger than the current Penny. There is a smaller vintage bag called a Dinky bag. Most versions of this don't have a removable strap.
The style numbers for these bags won't help you much because a lot of them were made before 1994 so the style number won't be in the creed.
@Whateve Thank you so much for the awesome explanation, I think the 9755 is what I'm looking for, will keep on searching

Thanks again for doing the authentication for people like us you guys really make buying used/vintage purse so much easy.
