In this case it isn't because it has already been seen when being returned by createInstance() - in which case the /Factory/ on create() should be removed. However for a different sub-class implemented in C++ then it would be the first time it was seen by Python so the /Factory/ on create() would be correct.

Perfect, that fixed the issue for me. Many thanks!
