If you have not already found them, there are three MCM's on Barnstormers. Two of which look like good candidates.
One [

Two [

The third has already been repitched to a 44 so may not be repitchable.
Without going back into the TCDS, are not MCM's and DCM's interchangeable? I wrote McCauley back when I was looking for a prop and asked once what the difference was between the MCM and DCM. The response was basically one had a "M" in it and the other had a "D". They are both manufactured from the same forging. I was just thinking this would broaden your search base.
