In 1850 (or thereabouts) the LB&SCR under the direction of J. C. Craven constructed some very large open thirds on a 13ft wheelbase. These carriages were essentially enlarged versions of the little 7ft 6in wheelbase open carriages of the early 1840s with their distinctive outside framing. The Brighton did not appear to be in any great rush to provide more comfortable accommodation for their third class passengers but gradually these opens appeared with roofs, some with individual pillars in line with the seat backs, and some with more dainty wrought iron supports. 
 

A braked version also appeared with a guards compartment and lantern lookout at one end, and in some cases a luggage compartment at the other. 
 

A fully enclosed second with the same familiar framing provided a bit more comfort. 
 

In the meantime the mid 1850s first class passenger could travel in luxury in one of Mr Cravens very modern six wheel carriages. The keen eyed observer will note the oval roundel. This is wrong, it should be round but I scratchbuilt this carriage about 15 years ago and have never quite got around to changing it. I really must get around to making that braked version of the open-sided third too!
