ok, I've just viewed some more pics, & I'm now a lot less sure about the ID of Lebanese Red:
1. The skin color is close, but still not quite right. Mine are more 'mottled' or banded, whereas LR looks more uniform and it has a stronger yellowey hue.
2. The flesh of the LR looks darker to me - possibly the reason for its name.
3. Leaf morphology looks quite different.
I think my search is still on. Either that, or maybe I'll just have to be content with TbF/Unknown.
