Marx Monon Line

I was posting all of the Marx O-Gauge Monon Line items on the Marx Facebook Group Page run by Johnny Thompson (awesome group by the way).  I thought I'd share the photos here too.  I think this represents all of the Monon Line items ever made under the Marx name.  The gorgeous hopper is a from the Flynn's Marx era, aka: Modern-Marx or Ameritrains.

Does anyone know of any other Marx Monon O-Gauge items?  I know there was also an HO diesel and work caboose, but I don't have photos or information.
The 6" tin 31055 Monon caboose is my favorite.  My 7" tin 3855 Monon caboose is a bit rough, so I'd like to find another.  I cautioned someone in the FB group that when searching for these, especially the plastic C-350 Monon cabooses, make sure to look closely at the rails on the end and the smoke-stack on the C-350 as they are often broken off.

Let me know if anyone has the 7" tin caboose, the hopper, the 4-wheel C-350, the 4-wheel tin Dummy, or the Monon wrap unit or wrap available.

Thanks, and Happy Holidays everyone!
