Reversed Label HP-41

[rprosperi]

The back of this unit (or maybe the whole thing) is almost certainly from a BlankNut machine; these came without a rear label installed, though one was provided in the box if the owner wanted one installed, and it seems these were often installed backwards.

It's also possible the unit went in for service and needed a new back, and the service technician installed it backwards, but this seems far less likely.
