Did you ever find out the details on this bag? I have the same exact one! I bought it secondhand, but it came with the orig price tag, from Saks ($1350), and model name says "Classic PM." I also bought the "Illusion" model, slightly larger, in black, with changeable panels for the outside. Would love to know when Saks was carrying Delvaux. They are exclusive to
Barneys now in the US. Really well made bags.
