B&M Trailer Trains

Here it is, its not a very good shot, unknown date. Click on the photo to enlarge.
The upper works were painted B&M Blue and the flatcar body was standard TTX boxcar red.

Were some of these racks repainted for Guilford? I remember stopping by E. Deerfield on my way to Vermont, in the early 1990s. I thought there were some in the R Yard.
