C31 modeling question

 nice work!  I also think that modifying the standard cupola is the
best way to go given the difficulty finding a Moloco kit and what you said
about fit-up.  I have a blue C31 in-transit to me; should arrive tomorrow or
Monday.  A friend is making the tank for both of us.


What blue paint matches the Atlas color?  Must be lacquer-based 
 I have no
experience (or interest to learn) with acrylics.  I only plan to modify the
side by cutting in new windows and patching the old ones so a slight
difference in blue tint can easily be covered with weathering powders.

I haven't been on this list for very long, but I've never seen it discussed.


I 3D printed the propane tank on Shapeways and used the Moloco cupola on
mine. I asked about it on one of the old Yahoo groups and Jonathan Vincent
collected some measurements for me. I got drawings for it from the NWHS.


Here's the 3D printed propane tank model:




And here's a shot of my caboose:




I didn't get the Moloco side filler parts to fit perfectly on my caboose,
but on subsequent models I've done a better job. The one beef I have with
the Moloco parts for this is the non-overhanging roof. It's good for the
Great Northern caboose it was designed for, but a stand-in for the C31. I'd
start with a standard cupola caboose if I were to build this model today,
but it wasn't an option at the time.

Has correcting the Atlas C31 cupola, adding the propane tank, etc. been
discussed on this list? �If so, what are the archives dates?� There is
no search option for multiple archives that I can find.� What�s the
recommended paint to touch up the modified cupola sides?
