If I remember the model is for FS2002 by Eric Cantu - Kittyhawk Studios, and very good it was at the time.
It holds its own in FS9
It appeared variously as FFX, too.
Never saw many repaints: I have Air Seychelles, Virgin Blue...
The Air Scheffel version is named after the author.
I was completely blown away by the interactive pilot checklist.
You can do your own thing and it will call out the full gamut of checks.
Or, if like me you have no idea where the APU switch is, set it to Auto and it will click them for you!
The panel transplants to the OS 737 quite well, save for elevator autotrim which tends to launch you vertically off the runway!
Edit: found a pic of the BBJ version (seen here having a moment at Boeing Field of all places), and it's not bad at all.
