.46 Extra Long box

Is anyone aware of a box label specifically for the 46 Extra Long? There is an overstamped 46 Carbine label on a box of appropriate height shown side by side with a Carbine box with the same label unstamped. I know this was a short-lived loading and I wondered if they just never made up any labels for it.

For whatever it’s worth I have the same box (just stamped in a very slightly different place) but no other for the .46 Ex L.
