I was about to suggest the Model G as well. Sounds about right - I suppose the low BB as Jose suggested?
I may also throw Bob Jackson out there as well. Their off the peg Vigorelly is about $650 shipped from the UK and the last time I talked to them about two months ago, the wait was about 10 weeks. Not bad and you get choice of paint color, lug pinstriping and decal.
Also: "Fully cast bottom bracket shell, crown & dropouts, also comes with 1 set of bottle fittings, drilled for front brake & takes 19-28mm tyres. Available with mudguard fittings for winter use at no extra cost if required."
