in fairness, and this is where forums are arguably a bit flawed, there is such a massive range of standards, knowledge and approaches to modelling - all equally valid given it is just a passtime - that we are never all going to agree.
One owner of a layout thread ive always really liked bought a much criticised loco. I said doesnt the flat front bother you and he freely admitted he didnt really know what the real thing looked like: He just liked models in their own right.
I do find it slightly odd when people get defensive and try to claim there is nothing wrong with something (different to saying they are happy with it) but lets face it, if we can be so far apart on how to run the country, a model loco is hardly going to be universally viewed!
