Looks very South African to me which means it might be a hybrid (just a guess) possibly natalensis x dielsiana? I think every grower has about 3 South African mutts in their collections! Hopefully Santa will bring you a nice digicam this season, and you will be able to show some flower details which will help to ID things more closely.
Thanks I believe you are on the right track, I got the plant in with a shipment of S. African species. It is currently putting up a scape so I will try to get some decent pics of the flowers to make it a bit easier.
