This is partly Verlinden's interior, but it took quite a bit of scratchbuilding to bring it into correct specs.
..with the engine installed...this is a separate kit, by the way...
I cut the roof out and opened up all the hatches to show it off...this is a command version, from DML.
This model was on the cover and the article in two parts, ran in Finescale Modeler, December 2008/January 2009, and is still available in back issues!
Here's a link to the interior build to help you a bit more...

The Verlinden stuff is still available--try eBay if you can't find it in stores!
