Frame strengthening plates are different too. On COT there are two separate strengthening plates over the axle boxes on the left/firemans side ( a stage 3 repair I believe), whereas on the right/drivers side, it is one continuous plate (stage 5 repair). The two sides are totally different, faithfully recreated by Bachmann. Photo evidence may reveal two locos the same, but the repairs were made as required rather than a preventional cure to the whole class.
I am sure it has been covered before, but the red frame locos did not receive the top feed pipework leading to the safety valve until later after 1911, at a time that the simplified livery was about to appear. COT had no topfeed during the time of the high speed mails run. It has been written that COT only received the earlier livery in order for the original number of 3440 to be used. In 1957, the BR books already had a 3717 in the form of a Pannier tank. (now there's a marketing opportunity for Bachmann to produce - both 3717 locomotives in a boxed collectors set).
Non of this is going to stop me buying another one (or two) though.Etched plates for 3712/6 already ordered.
I think it's more than fair to say that to strictly accurately represent almost any (?) member of the Class at some time in its original working life the Bachmann 'City' will require a bit of work unless one is satisfied with a simple rechristening and ignores the pattern of patching. But I don't think this would necessarily harm sales as Mike's post clearly demonstrates.
And I truly hope that the level of sales will encourage Bachmann or somebody to produce some coaching stock to go with the locos and suitable for at least one point in their lives - I'd like a suitable looking train to go with my two 'Truros' Alas as it looks like a very heavy Western (Region) year rapidly coming up over the horizon I don't think I'll be going for locos this far out of my chosen field and not quite so suitable for 'railtour' use as the first NRM loco (even if the frames are the wrong colour).
