You can pick this Flash up as No.1138 in Colin Owen's Book.

Michael reckons that this Flash is quite rare.........I have to agree with him.........I have not bumped into it before.
"Quartermaster's Comment":- Quite a busy Flash as far as the design goes......Were  they down in the Cape.......with Table Mountain in the background???......In nice condition and all three pins intact. Comes, as all do, with its brass metal fasteners.
