Western Thunderer
I am painting my N7 as Stratford engine 69712, I want to highlight the smokebox ring, I believe they were not painted but the ge boys burnished them.
so at present the loco is sprayed black.
I am wondering should I paint the ring or use a scapel to scrape off the paint back to whitemetal.
obviously this will all be varnished after transfers so the whiemetal should stay nice and clean.
the other thing I thought Imight do is paint the coupling rods red, another ge tradition.
I no in br days things wereclet go but have seen photos in the book On Great Easternlines by Peter Swinger and it shows a J17 in workhorse condition withcpainted rods, I just thought it mightclook neat and I would like to keep it in a reasonable clean state
