Used books of 1922.

Does anyone out there know where I can lay my hands on a copy of The Outbreak on the Witwatersrand, March, 1922, book by Capt. William Urquhart? It was a hundred-page book published by Hortors, Ltd. in Johannesburg. There's an OpenLibrary page for it, but I can't find any copies on AbeBooks or any of the other used book services- including one I found that searches South African bookstores.

I would settle for a university library or other library that would allow me to borrow a copy for a time.

Thanks.
