105 is the last of the truly original 1960's Barns, although it is seen here after a very comprehensive rebuild with a toilet in place of its 1st class compartment in the centre and new style half windows replacing the orginal louvres - it was the last of the carriages to retain these I believe.
It still bears witness to its original, and somewhat pioneering condition, when it had a chemical bog at the bottom end of the carriage - there is still an extra window pillar to be seen on the seaward (or engine)side of the carriage.
106 is a total rebuild of the original carriage with a completely new body but to the same outline.
It was followed by another new Barn, 107, before the advent of the super-sized, Super Barn design.
Both these carriages are running on my new brass / resin FR bogies (available to buy from Narrow Planet, by the way) and they just require the fitting of brass grab rails and a coat of varnish to be declared fully finished.
