How common were the evenly spaced roof hatch versions? I thought this would
make a good mini kit. That would save me from rearranging the hatches!

Clark,
These were relatively uncommon. GM&O had several series as well as one series
for M&STL and one series of SHPX cars. There may have been others but I've
not come across photos or freight car diagrams of every series to verify the
configuration, particularly cars built by GATC since the GATC builder's
photos seem to have fallen into an abyss.
