Whilst not our scale this German retailer has some interesting items:

I particularly like the Segment Turntable (200Euros though)
George might like the Trestle Bridge Kit - no price shown as yet.
The draisine looks good too, couldn't work out price of that - Gn15 version wouldn't be too difficult to model.
German not required on this site apart from pricelist
