I guess the equivalent to the would be the Borneo - it has large front and top doors but is also very tall unfortunately. I don't know who makes the Alaska either - possibly Skyline?

If you download Skyline's catalogue it doesn't even list the Barney and Alexander, just the Kerry, Leon and Tilo (the Tilo is basically the Barney but isn't made any more). So it's possible they make the Alaska as well although it does seem very different. I think a lot of these things aren't sold under the actual manufacturer's name. For example the Borneo was sold as the Skyline Speedy Gonzales - same cage but with a different coloured base and an extra shelf.
