Cascade / stealth model script example for OpenMx

I hope everyone is healthy.

I have been looking into extended family design, starting with S Medland papers [1,2]. Also, M Keller have some basic scripts [here](http://www.matthewckeller.com/html/cascade.html) which does not specify Medland's model completely, nor the Stealth model. My question:

- Does anyone care to share a script example for training purposes on either/or models? Or point to where I can find these?

Many thanks,

Luis

**Edit**:

- ~In which paper the stealth model was first introduced?~ Found it later in the body of paper [1]
