Dave -
I don't see them in the photo. ;D
By the way, how is the reefer or RBL etching coming along?
My bad.

You can see them called out on the track map (right click to view image at full res).
According to Wikipedia there is reportedly one remaining Griswold in operation in Tacoma. Have you seen it?

As for the RB project, I haven't integrated the etchings onto the sides yet. I had planned on laminating it on, but it looks bad. So I will cut out the plastic sides, laminate the etchings onto styrene, and then glue that in. I got distracted building the frame for this module, work travel, and the holidays but maybe this weekend I can make some progress.
Best wishes, Dave
