Old railway carriage seating model?

[tricky]

I have been looking for a cheap (or better, free!) 3d model of some kind of seating from an old train carriage. Not had any luck so far. Basically, its for a local artist who is designing a sculpture in a shopping arcade. Its a bunch of seating based upon an old fashioned railway carriage.

Does anyone have or know of anything suitable?

Cheers
