The ones I bought all have conspicuity stripes. The conspicuity stripes were required on all trailers built on or after December 1, 1993. if an older trailer was being used in interstate service (one built prior to December 1, 1993) it was to have the conspicuity stripes added by June 1, 2001. Since many of the decorated trailers are in "fallen flag" paint schemes dating from the 1960s, those trailers should be good for that time period on. However, 40-ft trailers were becoming common by the mid to late 1950s, at least in the western states where length limits were less strict. There is not much published information for flatbed trailers, so my information was gleaned from the numerous truck books I have, and from memory. However, I trust the books more than my memory.

I think this is the first time a manufacturer has attempted to include rub rails on an injection molded plastic N scale flatbed trailer. My guess is that the tool maker dictated the thickness of the rub rails to limit the number of rejects due to breakage during the manufacturing and painting/printing processes. Carter
I cant really fault the effort. To do this in N Scale is great . I just wonder if molding in the stake pockets and making seperate thin strips for the rub rails as detail pieces might have looked better. Modelers get all wrapped around the axle about 'thick' details on locomotives and rolling stock...why not truck parts? I dont think modelers having to shave off the rub rails...leaving the stake pockets...and using a thin styrene strip for the rub rails after buying them is going to be a deal breaker. The trailers look really good in the pic. I drove flatbeds all around the US and Canada for 25 years...I have a 'thing' about em. I am sure I will be buying some
