Yes, would take all of the above especially B&I. Perhaps dropping the container CAD/ model onto existing rtr CiE truck model to see if they would seat correctly?
I think thus would apply to other items also even back to 50s era era coaching stock. ... some background on the significance of the model with some good photos of the prototype in use will greatly encourage interest. Let’s imagine Murphy Modeks had not produced the 141, well, you see the point .
Nice looking model, even before painting. And I’d take some Bedford trucks too ( in CIE), or a cement truck to go with all those bubbles!
