Hi Bertram,
The "Delay" actor in your model has a _icon attribute that sets the icon.
I suspect that this model was copy and pasted from a Ptolemy model.

The "SampleDelay" actor xml is below. Presumably it is getting
its icon from a SVG file somewhere.

I tried searching for SampleDelay and dragging in the actor and it got
the right Kepler icon.
I also tried opening up a Ptolemy model that has a SampleDelay actor and it
got the right Kepler icon.
In Kepler, I don't think the user can edit the icon from the UI. In Ptolemy,
there is an icon editor.
