I recently bought a plastic display and a Heuer dealer stand. The seller got these stuff in a lot from an old Heuer dealer. The seller told that the old dealer sweared that the red display came from Heuer. It hasn't any markings or codes on it, the front has a recessed space for a large sticker that (I suppose) was never attached.
Have You ever seen one? Would also be interesting to see other vintage displays pictures.
Thanks!
