Hi there Alastair
i have also modelled this loco in 00 ready for my next layout, a model of the coal drop into the canal boats at crigglestone you will find this in the layouts bit of the forum if interseted.
all i have done to mine to make it same as the pics is:
Removed all the vaccum system large ejector and vaccum pipes off either end
added water capacity plate on the bunker
added patch on bunker
removed coal rails
added sand box on the fron L/H side of the running board
added fire irons and tail lamp as per pictures
weathered it to suit pictures
and painted coupling rods red
ill post some pics shortly its not perfect but its not bad either
Yeah 47445 belongs to my local railway butterley its undergoing major overhall which includes alot of new frame parts as well as the boiler being well past it but i look forward to firing it when it comes back into traffic the blue 3fs abit boring now days
Thanks Adam
