I love a good model - in any size - and I've had a soft spot for the WD Baldwins from my youth. I built a 0-16.5 Wrightlines kit nigh on 35 years ago, so when Bachmann produced a 009 version a couple of years back, I acquired one as a matter of principle. Yesterday I dug it out of the cupboard and had a good look at it. It was the Ashover 'Bridget' varient - clean and black, but it was on offer at the time. I can never resist 'setting to' when I get my hands on things - even if I'm not planning to build an 009 layout in the next few weeks........
First thing was to rub it down and polish it (counter-intuitive, I know) using 3000 grit W&D, and get rid of the printed name plates using a wipe of brasso and a cock-tail stick cut to a chisel edge, which seems to provide enough grunt to work away at the print, but leave the paint untouched (certainly in this instance). I then gave it a polish panel by panel with a wipe over of brasso followed by a cotton bud for buffing. Weathering was using water soluble oils brushed on over seams, top and bottom edges etc. and wiped off with a kitchen towel vertically, and often floated into inaccessible areas. This was followed with powders.
Brasswork and copperwork was overpainted with brass (and copper)mixed with gunmetal-metalcote to darken it down. More, and more subtle work could most certainly be done!!!
I replaced the couplings which really do stick out with ones made from nickel-silver which are much shorter, and added a whistle cord, and that has been it.
My point in posting this is simply to say - what an extraordinarily good loco from Bachmann! I find it wonderful how much the RTR stuff has come on, and how fortunate we all are to have this sort of thing available..!
