Too bad this isn't the MFCL where Dick Dawson probably could explain the technical
differences between different door designs.
You may be correct about the "different times" since I imagine the production machinery
for these steel products probably had to be replaced now and then... so why not tweak
Another reason might be different production facilities - or even licensed production in other
Ed Hawkins might know. Or maybe the answer could be found in contemporaneous engineering
publications like Railway Mechanical Engineer.
In general I don't waste time thinking about such things. The 'appearance' of things is all that I
really care about, as a modeler. Why are they the way they are? Meh. :-)
