Crank replacement

A quick learner from California says:
The crank mechanism for this unit hasn't been working well and the handle was then broken...
Wondering if you can tell what type crank I will need just from a image... If not I'll get the numbers later this week...
Much thanks!!!!

Hello, Joe. This looks like our 39-555 Velux skylight operator handle. However, if all that's broken is the stem, perhaps you can get away with just replacing it with our 39-550 adapter.
A contractor from California says:
What replacement crank do I need if I just want to replace the whole thing???

That would likely be our 39-405 Velux operator. This works with our 39-555 handle.
