I've just about finished the build of my latest pair of 'Barns' - the FR's new / old observation carr. 123 and the latest incarnation of 106.
The last remaining task - apart from fixing on the roofs - was making up some vacuum pipes and bonding them in place.
We make our hoses - or 'bags' as they are known on the railway - from wire stripped from old Peco point motor coils, wrapped around 0.7mm brass rod.
You might notice that the vac pipes run along opposite sides of the carriages - another of those FR carriage details that you have to watch carefully for.
I've another pair just like this being painted (by me) at the moment (for a client) but these two below will soon be sent south for Himself to finish off.
