From what I can see you did a great job painting those F units.  I've seen that scheme on DRGW 1st-generation hood units, but this is the first time I've seen it on covered wagons.

Might I suggest mounting your camera on a tripod when you shoot these videos?  With the train bouncing randomly around the different corners of the screen, it's a bit rough on these old eyes to watch it.  But keep up the good work and thanx for sharing.

I often use a tripod, and should use it more, I do understand that, all the F units from the FT on through most of the F7's, and the PA's and PB's were painted in this scheme, the FT's were slightly different in their paint scheme, but thats where the black and yellow scheme originated on the D&RGW.
