Interestingly not just the same G upside down like the one three rows below.

According to the Wikipedia entry about Eng printers used to substitute a rotated G in fonts with no Eng.

I believe the table depicts the alphabet of the language Luganda.

That lower-case variant is something else.

I believe James is right about it being an Eng.

i'll third that as an Eng

And I officially call an eng to this thread.

Dang ambiguity.

When I said the lower-case variant was "something else", I meant it was a crazy-looking letter, not that it wasn't an eng. Sorry for any confusion.
