In the UK, does "bread-bin" (as an adjective) mean "ordinary", or perhaps "stock"?
I think it might be a generational lapse, rather than a geographic quirk, as bread boxes don't seem common in younger households.
Still puzzled about the hole in the bottom - I wonder if it was being used in a business for some special purpose?

The other case variant is the Commodore 64C, which has a slimmer and more Amiga-like profile.
Thanks everyone; that was really stumping me. Now I'm still laughing.
