I just received my kit for one of Deerfield River Laser's new closed vestibule passenger coach kits! It looks great, should be as easy to assemble as their other kits and requires a Bachmann passenger coach underframe and roof for this particular conversion - 34 foot.
A quick read through of the instructions indicates this should assemble into a nice, different narrow gauge coach without too much trouble!
Will try to post photos when finished with this week's new project!
This particular coach is based on an ET&WNC coach!
